Hm, interesting bug. If you go the the URL http://www.compareindia.com/products/laptops/, then it works fine in Chrome. However 
using the URL posted in the original report or by going to 
http://www.compareindia.com and then selecting 'Laptops', leads to the broken 
behavior which spandit mentions above.

can't reproduce this with http://www.compareindia.com/products/laptops/# and 0.3.155.0 (Developer Build 3632)

I've been seeing this quite regularly.  For example, in Flickr, if you add a contact,
there are a pair of checkboxes offering to mark that person as friend or family;
neither are visible in Chrome.

I can't reproduce issue in http://www.compareindia.com/products/laptops/#.
As for the flickr issue, cdberry, can you add the series of steps to repro the issue?
Thanks for your report.

I have this same problem with all of my machines running Chrome - both at work and at 
home.  I'm yet to find a webpage where the checkboxes work.

This issue is *not* permanent, so it's hard to reproduce.  I've seen it affecting 
checkboxes, radio buttons and some tiny IMG elements.  After each OS reboot, for a 
while Chrome behaves just fine in this respect.  I didn't figure out what triggers it 
yet, but at some point Chrome starts to no longer display some of these elements any 
more.  I've seen it affecting (among other pages) the checkboxes on Gmail, radio 
buttons on the Netflix plan selection page, and the "+" that expands a transaction on 
the "recent activity" page of the American Express website.  It doesn't always affect 
all sites at the same time.  Here's how it behaved on the American Express website a 
bit earlier.

The attached file "ChromeIssue3543-NormalPageView.png" shows the normal view of the 
page; the circled "[+]" elements are small IMGs that when clicked expand the row to 
show transaction details and turn into IMGs looking like "[-]".

The attached file "ChromeIssue3543-BogusPageView.png" shows the bogus page view with 
the inspector on top -- the "[+]" looking IMG is not showing.  The DIV in the TD is 
highlighted, yet there's nothing to highlight when I hover the <A> in the inspector.

Interestingly enough, there were 2 ways to "fix" the behavior, with different 
"persistence" levels in time.

Option 1: I Alt+Tabbed to Firefox, navigated to the same page; the page was displayed 
normally there.  Alt+Tab to Chrome, refresh page, the "[+]" magically reappeared.  
This is temporary however: Alt+Tab back to Firefox and close it.  Refresh the page in 
Chrome, and the "[+]" IMGs are gone again.  (This temporary fix worked for me using 
IE instead of Firefox in the past.)

Option 2 (tried it later): In Chrome, I took the URL of the missing IMG from the 
inspector and navigated to it directly, as shown in the attached file 
"ChromeIssue3543-AccessingTheImgDirectly.png".  I switched tabs back to the AmEx 
page, and the "[+]" IMGs reappeared there.  They stayed there even after closing 
Chrome and restarting it, and even after clearing the cache (just the cache, not the 
browsing history).

At this particular time I can't reproduce the same behavior with the checkboxes and 
radio buttons -- on Gmail, Netflix or on the website initially mentioned in this bug 
report (compareindia.com) everything works fine.  The issue with IMG may or may not 
be the same as the one with radios and checkboxes, and actually it may or may not be 
a rendering issue(!) -- after seeing option 2 above, with the IMG it could as well be 
a HTTP issue (and perhaps  with radios and checkboxes as well, if Chrome is sometimes 
downloading the look and feel images used to display standard elements like radios 
and checkboxes).

Note that with radios and checkboxes, the elements seem to be there even when they're 
invisible, so if you know where to click they change state or do their actions.  With 
the IMGs on AmEx on the other hand, clicking anywhere doesn't trigger the action of 
the <A> (perhaps because it's too small without the image and I couldn't click it).

This issue disappears -- for a while, usually several days -- after an OS reboot.  
I'm using Chrome 0.3.154.9 on Win XP with SP3 (which I used to not reboot for weeks 
until I started using Chrome, so now I have to reboot it once in every few days).

The only other software I can think of that could somehow interfere with Chrome 
regarding this behavior is BitDefender Antivirus 2009, which every now and then 
quarantines a file in Chrome's disk cache when I access a page containing some form 
of malware.  The missing elements Chrome issue seems to me to happen more often than 
these malware removal events though, so there might not be any relationship between 
them.

I confirm this problem with Chrome 0.3.154.9 on Windows XP Home Edition SP3.

I've got Chrome in a cycle in which I could reproduce the invisible checkboxes / 
radio buttons issue any number of times on the following pages:
 - Gmail inbox: checkboxes next to each email are not showing
 - Netflix "change plan" page: radio buttons are not showing
 - compareindia.com -> "Laptops": checkboxes not showing, as well as the arrows (but 
only the tiny black arrows!) on the scroll bar buttons -- see the attached file

1. I start Chrome and open any of these pages.  The checkboxes / radio buttons / 
scroll bar button arrows are invisible, and stay invisible after a page refresh.

2. The checkboxes start showing up one by one when hovered with the mouse as soon as 
I perform any of the following operations:
 - in Chrome, open the "downloads" or "history" tab
 - in Chrome, open the "options" or "clear cache" dialog
 - in Chrome, open the "view frame info" and then "view certificates", *only if* I go 
to the second tab and have a text field/area grab focus
 - (note that any other things that can be open from Chrome have no effect though -- 
new window/tab, js console etc.)
 - click the Windows "Start" button to show the start menu, or press the "Win" key, 
or Win+R using "Win" as modifier
 - (however, Win+D (show desktop) and Win+L (lock screen) have no effect; nor does 
Ctrl+Alt+Del followed by Escape)
 - right click & properties on the desktop, the taskbar or any folder on the desktop
 - double-click to open the taskbar clock
 - open any folder using a desktop shortcut, including the recycle bin
 - open the "open" or "save as" dialog in another application (I tried in Notepad++)
 - open ProcessExplorer (which replaces the task manager on my machine) with right 
click on the taskbar or with Ctrl+Shift+Escape
 
It seems to me that the checkboxes / radio buttons / scroll bar arrows start to show 
up again on mouse over after any operation that shows a focused Windows component of 
a certain type (text field, text area, even the start menu).

3. The checkboxes disappear again when I restart Chrome, and the cycle can be 
repeated indefinitely.  (I repeated it many dozens of times to test all the things 
above.)

As a separate note, while all this is happening, the problem with the [+] icons on 
the American Express website that I was mentioning earlier doesn't take place at all 
-- the [+] icons are displayed properly even when the checkboxes and radio buttons in 
the aforementioned pages don't show.

Subsequently, after a reboot I can't reproduce the issue any more (as usually).

Neither : http://www.compareindia.com/products/laptops/#

Maybe this has been fixed in between 0.3.154.9 and 0.4.154.29.

0.4.154.29 on my end and Chrome does it on Gmail and other places. With invisible 
radio buttons you can do next to nothing on many online services. Not to mention 
Gmail itself, as the Settings pages become useless.

I also get it randomly on some pages. I just got it with the netvibes login page 
where there was a checkbox for "remember me", i have version 0.4.154.29

I've got this in two systems running 0.4.154.29, on WinXP Pro SP3, running for 19 
days, and Windows MCE 2005 SP3, running for a week.
It does seen related to longer running times for the machine. Usually, changing from 
maximized to normal window and back causes the check boxes and radio buttons to 
render. Kinda reminds me of the behavior of Win9X after showing the "Dangerously Low 
on System Resources" message... Quite annoying.

My father is having this issue too in 0.4.154.29.  This is a serious compat issue 
that prevents users from using most of the web.

I've been able to consistently reproduce this on 0.4.154.31.  The checkboxes 
disappear after visiting a page with Flash content, like YouTube.  Restarting Chrome 
doesn't bring them back, but starting IE7 and visiting any page will cause Chrome to 
render properly again.

I had this issue since I downloaded Chrome on launch day. It's a sporadic issue, but 
occurs on just about every page that I visit that has radio buttons. My version is 
0.4.154.31, running on Windows XP SP3.

I also see this problem with the latest dev release.

The latest trunk (6490) also has this problem.  From a fresh mini-install, here are 
simple steps to reproduce:

1) Go to GMail.  Checkboxes appear.
2) Go watch a video on YouTube (Flash)
3) Go back to GMail.  Checkboxes do not appear.
4) Even restarting Chrome, the checkboxes do not appear.

I'm seeing this problem wit 0.5.154.29 as well on many different web pages,
including gMail.  Problems comes and goes randomly; restarting the browser
does not seem to help, nor does uninstalling and reinstalling Chrome.

On thing I noticed:  Even though the radio buttons are not visible, they are
still there.  On the gMail inbox estimate the approximately position of the
checkbox next to the message and click - you should see a faint image of a
square.  If you then select an action from the drop down box at the top, it
will take effect on any messages that you've checked.

I can expand on gregsch's (comment #19) observations:

(a) You don't actually have to watch a YouTube video - just going to
    It seems like opening up certain web pages will break it.  Note
    that you have to actual open the page.  If the page is already
    open, merely refreshing the page will have no effect.

    Pages that break it:
    http://youtube.com
    http://nytimes.com
    http://foxnews.com
    http://cnn.com
    http://amazon.com

    Pages that don't break it:
    http://att.com
    http://apple.com
    http://maps.google.com
    http://adobe.com
    http://wal-mart.com

(b) Once the objects disappear, opening up windows task manager 
    (ctrl/alt/del) will bring the objects back.  (You have to 
    refresh to see this).

(c) If you leave the task manager window open, the objects are immunized
    from opening the youtube homepage.  However, the window must be OPEN 
    and not minimized to the task bar.

(d) If objects are missing and the task manager in minimized, restore the
    WTM window will fix them.


I did all my experiments with multiple tabs:
(1) Open gmail, checkboxes appear
(2) Open an offending web page in another tab
(3) Go back to the original tab and refresh, checkboxes are gone
(4) CTRL/ALT/DEL to open WTM
(5) Refresh gmail again, boxes are back!
(6) Close WTM
(7) Refresh the offending page
(8) Refresh gmail again, boxes are still there
(9) Close offending page
(10) Reopen offending page
(11) Refresh gmail, boxes are gone
(12) CTRL/ALT/DEL to open WTM
(13) Refresh gmail - boxes are back
(14) Leaving WTM open, repeat steps 9 and 10
(15) refresh gmail - boxes are still there (WTM protected them)
(16) minimize WTM
(17) Repeat steps 9 and 10
(18) Refresh gmail - boxes are gone again
(19) Restore WTM
(20) Refresh gmail - boxes are back!

This seems to be system dependent; I can reproduce it reliably with my home system 
but it won't happen with my office system.

I am seeing this for the first time with dev build 0.4.154.33, after having no such trouble since the first public 
release version (0.2.149.27). The behavior is as described by rjd444 in comment 22. The behavior is triggered by 
the websites he lists under "Pages that break it", but was observed before visiting any of the above (as I visit 
them only seldom); it appears to be triggered by a large number of sites, but I have not yet taken the time to 
figure out which.

Many small page elements disappear:
- checkboxes
- arrows on dropdown lists
- the "knurled" line effect in the corner of Chrome edit boxes (including, presently, the one I'm composing this 
comment in)
- arrows above and below scroll bars
The page elements are still active, but invisible. For instance, if the space that an invisible checkbox should be 
occupying is clicked, submission of the form to which it is related produces behavior consistent with a checked 
box.

The behavior reverts to normal if any browser dialog is opened. Context or other dropdown menus do not have this 
effect. Examples include:
- Bookmark dialog (click any star on any tab)
- Task manager (by any method)
- Options window
- Bug report window (which makes reporting by this method problematic, because screenshots do not contain the 
issue)
Opening any of the above elements does not cause any visible change to the current page's display; however, 
mousing over any affected page element restores it to normal. Switching to another open tab also restores the 
elements to normal.

The issue skates along the border between "frustrating annoyance" and "browser-breaking problem" for me; I'm using 
Chrome at work with Salesforce.com, where checkboxes are common and required for efficient usage.

Note that it is going way back, from the beginning or so. I thought it was just a

Now all of my windows *beside the about:network window* have no scrollbars arrows or 
checkboxes.

Could be a Windows XP Classic Theme issue (which I am using, too), as pointed out in

Yes, Windows classic theme here, too.

The issue has been occurring much less often on my machine in the last month or so, 
and I was wondering whether someone else could check whether when it does happen, 
switching to XP theme and back fixes the issue just like rebooting would -- which is, 
longer term than pressing the "Start" button or opening the same page in IE / FF do 
(i.e. just for as long as the page stays open).

If this works, then it could be an acceptable workaround for people who say they 
don't use Chrome because of this problem, provided that it doesn't happen to them 
more often than, say, every other day or so.

I would gladly try to do that myself (and will do so when I get the "chance"), but it 
may take days until the checkboxes, radios and arrows go missing again on my machine.

I am now at build 1.0.154.36 and I am unable to reproduce the problem any longer.

I still see this occasionally with Chrome 1.0.154.36 (runtime of 4 hours) on Windows 
XP SP3 with Classic theme.

I can sometimes reproduce using youtube, but not reliably. Ctrl-Shift-Esc for Windows 
Task Manager works for me as a temporary fix.

i am having the same issues. no checks or radios on gmail, netflix, flickr and many 
others. any ideas yet?

I can confirm this issue in Chrome 1.0.154.36 on Windows XP Pro version 5.1.2600 with 
Classic theme (fully patched).

Ah, interesting. Although the checkboxes weren't appearing in Chrome initially (see 
my comment above), they now are appearing.

Same problem here, extending to Gmail as with others (where the checkboxes are still 
live, but invisible).

Chrome 1.0.154.36, XP SP3 with classic theme.

This problem has never previously occurred for me (been using Chrome since launch, 
same machine, same version of Windows, same theme. Only recent change was the 
installation of a new monitor, which seems an unlikely catalyst).

Same problem here too. Chrome 1.0.154.36, XP SP3 with classic theme. Seen it in 
chrome since the launch on several installations of Chrome.

My scrollbars on the  bottom and the left of the page also don't feature any arrows. 
(see picture)

I should mention that I've also experienced the scrollbar arrows disappearing, in the 
same instance of Chrome that I reported about above.

I've been also been using Chrome since launch with Windows XP SP3, classic theme.

I'd not experienced this issue (checkboxes not rendering, scrollbar arrows not 
rendering) until yesterday. At the time I was using Chrome 1.0.154.36 and I've since 
updated to the dev build 1.0.154.42 which also exhibits the problem.

The emergence of the problem coincided with me updating my monitors' colour profiles,  
which may relate to yprbest's observation regarding changing his monitor.

I also have this issue using version 1.0.154.42
Windows Server 2K3R2 SP2

the task manager trick mentioned above worked for me.

Reproduced with 2.0.157.2 (classic theme, XP SP 3 pro, Gigabyte ATI X300).
Maybe this can help - I had five tabs opened on startup (from the  last session), one of 
them took a while to load and then when it did and the scrollbar appeared, it was arrows-
less. The is the website - http://www.mekusharim.co.il
Hopefully that helps.

I've just noticed an interesting correlation.

I haven't been encountering this bug for a long while (about 2 weeks), then several 
minutes ago it came back.  This is interestingly correlated with the fact that I 
haven't been watching any DVD movie in a couple of weeks, until last night when I 
did.

I'm currently using Media Player Classic 6.4.9.0, and until 2-3 ago I have been using 
VLC 0.8.6i -- which I think was causing the same issue. (I think they share codecs, 
so the actual player might not matter.)  I'm using both players with their default 
configuration.

Confirmed on Google Chrome 1.0.154.43, XP Pro SP2, Classic Theme.  No checkboxes, 
radio buttons, or scrollbar arrows.  Opening Firefox fixes it.

As an addendum - several times I went back to a fresh install (after leaving Chrome 
uninstalled for several days) with no joy. However, last week I returned once more, 
and everything was fine again: this came shortly /after/ watching a DVD for the first 
time in a good while on this machine.

As of this morning, the problem has returned (including missing scrollbar arrows), 
though I can think of no changes whatsoever to my settings that I have made. Also 
worth noting - once this problem rears its head (and this occurred with the earlier 
occasion, too), if I ignore it and continue to use Chrome for any significant length 
of time, opening new tabs, my machine will eventually succumb to a BSOD (generally 
after opening link in a new tab). Which is unusual, as my PC is very stable - it has 
never suffered any other BSOD's in its lifespan (built from scratch last July). Looks 
like I'm in for another uninstall.

I'm experiencing the same issue, as commented in this duplicate bug report:

http://code.google.com/p/chromium/issues/detail?id=6497

This seems to happen at random. Unfortunately I don't know of any steps to reproduce, 
but I can say that it will only affect certain tabs and not others. I may have 3 tabs 
open and only one is missing arrows/elements, or they may all be missing it. Closing 
and restarting Chrome/Chromium has no affect. Attached is a screenshot highlighting 
the issue.

This is definitely a problem for me also.
Windows XP SP3, classic theme.

I think this is a webkit bug because I had the same problem once using Safari on the 
iphone.

rjd444 (Comment 21) definitely has a point. The issue seems to be resolved (as a 
stop-gap measure) by opening the Windows Task Manager.

(No comment was entered for this change.)

This problem disappears immediately when I switch to the default, rounded, extremely 
blue Windows XP theme.  I usually use Windows XP SP3 in the classic (Windows 95-
like) theme.

First showed up for me with Chrome 1.0.154.48.

@57 - me too! It may be worth noting that on both computers where I've seen this issue, I've had the Windows 
2000 Theme enabled on XP. Perhaps it has something to do with that?

This issue of the invisible check boxes also inflicts my google chrome. Have seen 
this for many months now. Agreed with posters above. Opening Windows Task Manager 
makes the issue go away. At least temporarily. Issue does return at some point in 
time again. I am also in Windows XP classic theme. My girlfriend running Windows XP 
in normal mode and has never seen the issue.

From the Help Forum:
In Windows XP, the answer is to enable the following: Right-click My Computer,
Properties, Advanced tab, Performance Settings, "Use Visual Styles on windows and
buttons." This problem started happening when I turned off all of those options to
improve performance on my stressed system. I started adding things back one by one,
and since enabling that last checkbox, the problem hasn't recurred.

 Issue 8522  has been merged into this issue.

I think we are running up against the per-process GDI handle limit.  See http://msdn.microsoft.com/en-us/library/ms724291(VS.85).aspx

Using the option in Comment 63 may increase the per-process limit.  Likewise, opening 
the Task Manager may have a similar side-effect.

If you are seeing the problem it would be helpful if you could open the Task Manager.  
Go to View > Select Columns and make sure GDI Objects is checked.  Then look at the 
number of GDI objects reported for Google Chrome on the Processes tab.

I realize that having Task Manager open solves the problem, but I think if you open 
it while seeing the problem you will still be able to see the current GDI Object 
count.

It is possible to increase your GDI handle limit manually.  I would be careful doing 
this because increasing it too much could cause you trouble.

Perhaps Process Explorer (http://live.sysinternals.com/procexp.exe) can inspect the 
GDI handle count without interfering with the bug itself. This is just a theory and I 
can't verify it at the moment.

Any ideas what exactly Task Manager does that acts as a workaround? Does it muck with 
the GDI handle tables in any way?

(No comment was entered for this change.)

I think I have stumbled upon this same bug on an OSX build: "Chrome 2.0.170.11908"
But it seems to manifest itself slightly differently.

See Issue 9004.
I have confirmed that the same pages which do (and do not) trigger this bug (Post
#21), are the same ones that trigger (and do not trigger) the bug in issue 9004.

I just noticed this issue on 2.0.169.1/Windows XP Pro in Classic display mode.

Interestingly, the fix in Comment 63 worked for me except in reverse - I had all the 
options ON and turning them OFF fixed the problem.

This is a perpetual problem for me. I'm really glad to learn the trick of opening up task manager! It 
just worked for me. Usually I go into firefox for a page where I really need to see checkboxes.

The GDI Objects column ranges from 23 to 523 for the various chrome.exe processes with the median being 
around 50. Only 1 of them has more than 100. Eclipse.exe has 1121 (more than all of chrome's put 
together) so it's questionable whether this is the problem.

I'm using XP Pro, classic theme, Chrome version 2.0.170.0

 Issue 6953  has been merged into this issue.

I think it's a problem with "Adobe Flash Player". In most cases when I open page with 
flash on it, then go to other page (or open new) "everything" disappears (radio btns, 
check boxes, arrows on scrollbars). From time-to-time (it's randomly) when I hit 
Ctrl+A on bogus page without check boxes, they appear again. The "Task Manager" trick 
also works from time-to-time.  
Also.. Why i think it's "AFP" problem. When I open flash site or some page with many, 
many flash on it (Flash header, flash menu, flash banners) the CPU temperature goes 
really high (over 70C), but the CPU usage is not high (approx. 10-20%). This happens 
only with Chrome and from time-to-time, and not on the same pages.

It's really annoying... Because of this bug and one another with phpMyAdmin I don't 
recommend (yet!) this browser to my friends and clients.

This issue happens to me consistently at a fresh startup, no Flash involved. The GDI 
and USER object counts for the chromium processes are all very reasonable, so I am sure 
this is not a problem with that. XP SP3, classic mode (no themes).

hmm I don't think this issue has anything to do with the players, I opened a gmail 
tab, and then another google page, left it on for sometime, came back to my gmail tab 
and found all them checkboxes missing :( . The (slightly tedious) workaround for this 
as has been mentioned in great detail by  AndreiJuan is simply to go to a focused 
windows component, hit Ctrl+alt+delete and simply close the window, you'll find them 
reappear again. Could this be intertwined with the cache issue 
(http://groups.google.com/group/google-chrome-help-

Ben, please triage

 Issue 9192  has been merged into this issue.

I had this issue for about three weeks, it went away a few days back. This coincided 
with two major changes, one that was touched on above.
1: I cleared my browser cache.
2: Avast found a WIN32:CTX Trojan called A0153958.dll and removed it.
Other than that, I'm not sure what could have caused it. At the time, the radio 
buttons were always accessible just hidden and the scroll bars were functional as 
well. The ghostly behavior was just very unsettling as I am used to everything always 
being consistent on my pc as I'm sure many of you are.

Same issue here on 2.0.172.6. I don't have radio buttons, or checkboxes. This is a 
fresh full install of Windows XP SP3, then all latest updates applied. XP theme changed 
to "Classic" theme. The only applications installed are IE8 and Chrome.

Opening Task Manager as specified above, and then refreshing the page brings the 
controls back.

I've noticed this on 2.0.172.8 (according to 'about') but it's been happening for the 
last 2 months or so.  The ctrl/alt/del trick works.  When it's happening, i checked 
WTM, and none of the GDI counts were about 250(combined total less than 500.)  Outlook, 
as a comparison rolls with over 750.  Windows Classic theme.  

Confirmed that to fix this temporarily, just start taskmgr (no need to ctrl+alt+del, 
precisely), and reload the page.

Not a BrowserUI bug.

2.0.172.23 has this issue too, but the ctrl/alt/del trick works

I've also been having this issue. I'm using Windows XP SP3 and Chrome 1.0.154.65
Found this thread and decided to play around a bit. To test visibility of checkboxes
I used my Gmail inbox.

At start I was using the Windows Classic Style, with no Background image, but a user
selected color. Performed the below actions twice with same results except where noted.

Switched to Windows XP style. Able to see checkboxes immediately. Able to close and
reopen Chrome without issue reappearing.
Changed Desktop Color. Checkboxes visible. Able to close and reopen Chrome without
issue reappearing.
Switched to Windows Classic style. Checkboxes visible. Able to close and reopen
Chrome without issue reappearing.
Changed Desktop Color.  First time checkboxes disappear immediately, on second test
not till close and reopen. Close and reopen Chrome checkboxes still not visible.

Find that programs/windows (that are part of XP) open with checkboxes allows Chrome
to render the check boxes. Think this is why Windows Task Manager being open works as
there's a checkbox on the Processes tab. Also why going to System
Properties\Advanced\Performance Settings\Visual Effects and causing focus on the
scroll window there (whether by toggling a checkbox or just using the scroll bar)
cleared the issue. I also had this happen by having the Display
Properties\Appearance\Effects... window open.

Hope this helps.

Peter, can you look at this? Just trying to find the right person to work on this.

I'm convinced this is a GDI handle limit issue.  I'm also fairly sure Chrome itself 
is not at fault, but not 100% certain.

There are two GDI handle limits: one global (the "session limit") and one per-
process.  On my machine the per-process limit defaults to 10,000, and I think that is 
fairly true on other machines too.  Given what I saw in my testing and what people 
reported above, I don't think we're anywhere near this limit.  We could confirm this 
by instrumenting Chrome with histograms if we thought it likely.

The likely issue is that the session limit is being reached.  This goes up to 64k 
handles but scales down dynamically with memory.  If another app is leaking handles 
or simply using a lot we can hit this.  At that point various classic mode controls 
will fail to draw correctly.

If people can reproduce this at will (close Chrome and the problem disappears, open 
it and it reappears), they could try running without the sandbox to see if there's 
any effect.  Another thing to try would be the current beta or dev releases in case 
I've overlooked a fix for a handle leak.  The problem with these is that if the 
problem is somewhat fickle, we'll get bogus data ("the problem went away!" when 
something else changed).

nsylvain has a tool that can report precise handle usage of everything on the system, 
that perhaps we can have people hitting this problem run to see exactly what's going 
on.  Passing the bug to him to add this tool, plus any other comments, including 
whether he thinks any histograms or other work on our side would be useful.

The tools is http://www.nirsoft.net/utils/gdi_handles.html

If you have issues and think chrome is leaking handles, please run this problem and 
let us know which handle type seems to be a problem.

If someone can replicate fairly easily, feel free to email me off list to plan some 
debugging.

As for the histograms, we could always do it. not sure at this point if it's worth 
the trouble or not.  Let's see what we get from the tool first.

Seeing this on my work machine, which is a XP Pro x64 with classic Windows theme.

I have this same problem...

Windows XP Pro SP3

(No comment was entered for this change.)

some issue
windows 2003

I am having this problem using Chrome 1.0.154.65 running Win XP Pro 2002 SP3 with 
Classic style desktop and Standard colour scheme. Frequent lack of check boxes, 
causing seriously reduced functionality for many web sites, including Google Mail. I 
will have to switch back to Firefox.

It's very funny that chrome (the Google browser)
is not able to properly render gmail (the Google email) page.

I' using gmail at any time of my day,
so I will continue to use FF until this stupid bug is'nt fixed.

Everyone having this problem should run this tool and report which handle type seems to 
have a leak.  http://www.nirsoft.net/utils/gdi_handles.html

As we cannot reproduce it here reliably it is possible that there is something else 
being run on these machines that is using up the GDI handles. 

I've been having this problem a lot recently.  It happens pretty soon after boot with very few apps running.  evanm pointed me to this bug and I gave 
GDIView a try.  

The top 3 were:
Explorer has ~240 handles
A chrome process with 226 (19 Brush, 31 Bitmap, 82 Font, 2 Region, and 54 DC)
QuickCam software had ~130

There are a few more processes in the 50 - 100 range.

Killing QuickCam freed up enough to give me form fields and proper scrollbars.

Here's the report for all my current Chrome processes:

I didn't have this problem until I installed Avast (free edition). And when I run into 
the problem, I stop Avast (via systray), reload the page, and voila, the radio buttons 
and checkboxes are all there.

I am having this problem too, using the Windows classic theme in Windows XP SP. Using 
GDIView and closing some processes using the most handles appears to fix the issue 
temporarily. If I reopen those processes and load a problematic URL again in Chrome (in 
a new tab, not refreshing it), the checkboxes disappear again.

I am running Google Chrome 2.0.172.31 on Windows XP on an Acer Aspire One. Switching to 
Windows XP Classic causes this issue for me. Switching by to Windows XP the newer theme 
makes the button decorations appear again.

I'm running chrome 3.0.187.1 on xp pro. I ran GDIView and figured out the problem went 
away when I shut down outlook 2007. 

Any news on this one ? I am running Win XP  with the Classic Theme and Chrome 2.0.172.33 (latest version) and it's still here. The bug just comes and goes. It's hard 
to reproduce. Sometimes when you maximize or restore makes the bug go away.

Wins XP ,Chrome 2.0.172.33...This actually just happened trying to log in to post. The Check box for public Profile was invisible.(The Properties Taskbar W/O worked) It 
happens with some Myspace Applications as well. The Street Racing, Mobsters, Overdrive 
apps.Some sponsors pages don't show. Plus some questionaires have invisible check boxes 
or you don't even know there is a box that needs checked until you cant go to the next 
step of things. 

Also have this problem

Very major bug. I sometimes faced before chrome to hang but this seems more serious.
I have added all the workarounds to my blog http://arjudba.blogspot.com/2009/07/google-
chrome-problems-checkbox-and.html
Am I missing anything?

I repro this pretty easily on my work laptop. How can I help get it fixed?

I feel like the Peter's theory about the global GDI handle limit must be missing 
something because if I open Firefox, I get widgets fine.

I can confirm this bug. Running Chrome 2.0.172.33 on WinXP.
Cool that the Cancel-button in TaskManager solves the problem temporary (according to http://arjudba.blogspot.com/2009/07/google-chrome-problems-checkbox-and.html)
Hope this bug will be solved soon. Gmail and other above mensioned sites are useless 
without checkboxes and radios.

Sorry for not replying more often, i'm still really clueless about this problem.

aa: if you get this problem while you are in MTV, please bring me the laptop so I can 
take a look. And we should talk this week about your normal use case for your laptop, 
just so I can try to understand why I never had the problem.

Thanks

Is it possibly related to Firefox's Persona extension, where the status bar cannot be
skinned *only when using Windows Classic theme* ?

I experienced this too when using a quite clean install of Windows XP - only when the
theme is Windows Classic.

I'm experiencing this on ALL websites. Not being able to use forms makes the browser 
almost useless... Windows XP, classic mode, Chrome 3.0.191.3.

Obviously relates issues: 14302, 10821; should probably be marked as duplicates.

 Issue 10821  has been merged into this issue.

 Issue 14302  has been merged into this issue.

I am still having this problem in version 3.0.193.0 on XP SP3.

nsylvain: I will come see you today.

Seems to be an issue with rendering Marlett font characters in elements for whatever 
reason. All elements are affected -- radio buttons, checkboxes, combo box dropdown 
buttons, scrollbars, etc.

http://en.wikipedia.org/wiki/Marlett

I am also using the Classic theme in Windows XP SP2.

I wonder if we need to pre-load Marlett into the font cache, like we do for the other 
fonts...  Does the issue reproduce if you turn off the sandbox (run with --no-sandbox)?

I'm going to try that and let you know if it comes up again, since I haven't looked
for a reliable way to reproduce the issue.

In theory the preload should be automatic. here on my machine i can't load this font 
even in IE and firefox.

Ok, I started Chrome with --no-sandbox and spent about 5 minutes trying to reproduce
the issue by following the various instructions on this site (visit a site with
Flash, etc.) I was NOT able to reproduce it with --no-sandbox enabled.

When I restarted Chrome without --no-sandbox (no other command-line arguments), the
bug came up almost immediately -- see screenshot. I used this site as an example
because it uses virtually no javascript or CSS, eliminating any complicated bugs.

The radio buttons disappeared when I opened the tab with the YouTube video and
reloaded the page with radio buttons. They remained visible until I reloaded the page.

They /usually/ reappeared when I closed the YouTube video and reloaded the page
again, but sometimes stayed hidden. This seemed to be determined by whether the page
was being loaded from cache or reloaded from the site.

Perhaps helpful: The bug only manifested itself if the video was loaded in the active
tab. So if I started loading the YouTube page but switched away from it before the
flash object started loading, the bug would not happen. Even if I switched to the
YouTube page and then switched back to the radio button page, the radio buttons
remained visible. They remained visible even if I *reloaded* the YouTube page (F5) in
the foreground. However, if I closed the tab and re-opened it with Ctrl+Shift+T and
let it load in the foreground, the radio buttons would disappear again.

I could be wrong, but it now seems to me like it could be a layering issue where
Chrome is deciding to hide the radio buttons because it thinks they should be behind
the flash object? I'm not sure, since scrollbars are also affected.

thanks for your detailed comments! However I still can't replicate !

Instead of --no-sandbox, can you try --disable-winsta ? 

And then, can you try --disable-job ? 

Thanks again,

Nicolas

Nicolas, are you running the Windows Classic theme on XP? That seems to be what most 
reporters are doing.

You can set it in the Display control panel, Themes tab (first one.)

I usually don't run with classic mode, but to try to replicate the bug, I had classic 
mode. I'll keep it enabled until I can replicate the bug!

I completely forgot to mention that I'm running Chrome 3.0.193.1. Hope I didn't send 
you on a wild goose chase.

Nope. I'm running the same version.

there are invisible checkboxes in 3.0.195.1 winXPSP3 classic mode

i too have this experience.. See this website :http://www.trip-to-india.com/cities/

I also have this problem, again using winXP sp3 classic mode chrome 3.0.196.2 (have 
redirected user files to custom folder due to roaming profile issues)

It once happened a lot to me, but now, with the beta channel in dev branch, at version 
3.0.196.2, this bug seems to be gone since 2 weeks ago.

this bug appeared in 3.0.197.11 again

another possible duplicate: Issue 19251

Seeing it in 3.0.195.6.  Previous resolution of opening up Firefox, navigating to the 
same page, and refreshing the Chrome page does resolve the issue.

Reference: http://www.google.com/support/forum/p/Chrome/thread?tid=0551a15ebb64a498&hl=en

What is the expected result?
Radio-buttons, Check-boxes, dropdown-selects and scrollbars should be visible.

What happens instead?
Radio-buttons and Check-boxes are completely invisible.
Dropdown-selects and scrollbars don't show directional arrows on the 'up' and 'down' 
buttons.

possible.
If this problem occurs, It immediately affects all tabs.

You wouldn't believe it if you see it, but I started Safari to test the if   the 
would reappear effects. And now all the problems are gone, so I can't create a 
screenshot.

(2 minutes later)
I tried Opening GMail and the problem was back again, I tried to make a screenshot. 
Guess what happened, the problem disappeared again. If I'm not mistaken, after I 
opend Photoshop. I think it looks like a "redraw"-problem.

For illustrative purposes, I'm going to photoshop how the problem looked like. Before 
it automagicly fixed itself.

I couldn't find a sollution before, but since I tried to make a screen shot and test 
it in an other browser the "drawing" within the elements fixed them selves. Weird, 
that unrelated software can have such a big influence on Chrome.

 Issue 19501  has been merged into this issue.

Yes, I have seen this on Chrome 2.0.something and now on 3.0.195.6 aswell.  If anything 
though it seems more prominent now.

Not just Gmail affected, once it happens it happens on all tabs.  Very annoying when 
filling in forms and you can't see radio buttons or checkboxes if there isn't any 
obvious text right next to them, or the layout is wonky and the controls don't appear 
where you expect them to be.

Same issue here, Windows XP sp3, Chrome 2.0.172.39.  Missing arrows on scrollbars and 
combobox pulldowns, missing checkboxes.  Happens on about 50% of page loads here, 
regardless of other applications that are/are not running.  Only affects Chrome, not 
other apps.  Running windows classic mode UI, with themes service turned off.  Should 
be easy to reproduce if you run XP in classic UI mode, and just browse around the web 
with Chrome for a while.  I'm seeing it on two different machines.

I think it might be a bitmap leak in the main process (pid 1480 here):

The (kernel) handle count is hovering suspiciously around 990 but I was able to push it up 
to 1080 by opening a tab. I was going for a ceiling at 1000 or 1024 but it's probably not 
the case.

 Issue 20745  has been merged into this issue.

After about 2 months of using the windows xp theme, i switched back to windows classic.   
Currently, i'm running 3.0.195.10, no other change in usage patterns on the machine, 
and I no longer experience this issue.  

I am running 4.0.207.0 (25586) and issue is still present, the checkboxes are missing. 
I have themes disabled under Win XP

Recently worked on a client company, 15 terminals, Windows XP fresh installation:

- Windows XP Professional SP3
- Classic Style View
- OpenOffice
- Net framework 3.5
- Firefox
- Acrobat Reader 9
- Chrome (ovbiously)

Nothing really out of the common, I still not even installed Antivirus.

Im using for google Apps for the company domain, was planning on replace the mail
client by the Chrome Web App mode, but this is a pain.

Oh forgot to comment, I've downloaded a redistributable version of Chrome for this,
although it was from google.com (dont have the link at hand) and seems to be the
latest version to the date (2.0.172.43).

There is a little anomally with it though, it says "Cant update the server (error:
3)" at the About Google Chrome dialog.

It could be a problem with "Adobe Flash plugin" as some of others have stated. 

When I "kill" the flash plugin using chrome's task manager (shift + esc) check boxes 
and radio buttons become visible again.

(Using 4.0.206.1 on Windows XP classic theme)

I am currently running 3.0.195.6, and have had this symptom 99% of the time with every 
version of Chrome I've had.  Windows XP Pro SP3, Classic style.

But based on yesterday's comment I decided to see if I had an Adobe Flash plugin 
running.  I do not, but I've noticed that simply launching chrome's task manager is 
enough to make the missing elements render on any open tabs.  Reloading the page on a 
"fixed" tab retains those elements, but launching a new tab to the same page reverts 
to the broken behavior. 

Running 2.0.172.43 -- I see this very very often.  Gmail doesn't show checkboxes, 
scrollbars have no arrows, kayak.com is missing radio buttons.

Thus I cannot use chrome to manage email, buy flights, shop online, etc. -- please 
treat this as a top-priority bug.

I'm running 4.0.206.1 on Win XP SP3, and sometimes(!) the checkboxes and radio buttons 
disappear.

Like today in Farm Ville as I was sending gifts... :D

*** IT'S BEEN ONE YEAR (1 YEAR) since this bug has been reported and NO ONE at GOOGLE 
did NOTHING to fix it! Well done Google, this is the way! Going back to Firefox. No 
second thought. Running Chrome 3.0.195.17, AND HAVING THE SAME PROBLEM. ONE YEAR PASSED 
and not fixed! Ashame people. Ashame Google!

I thought I was the only one.  This is making Chrome unusable.  How can a bug this big 
make it from beta to version 3.0.172.43 without getting fixed.

Now even restarting my computer doesn't fix it (thought that worked for a while, 
inconvenient as it was).  This is the case on both my Vista and XP machines.

@toddlando: The current workaround is to not use classic theme.

Rest assured that multiple people (including me) are trying to fix this problem.  I still haven't been able to replicate 
(some other people did though), so if you think you understand why/how it happens on your machine, please let us 
know.

As for vista, you are the first person to report the problem, everyone else is XP only. I suspect this might be a different 
issue.

Thanks, and sorry for the trouble.

Nicolas

I had this problem for months. I found a workaround, and it is sort of a habit for me 
now. When I find a checkbox that should be there but it is not, I quickly open the 
Windows task manager with Ctrl+Shift+Esc. Just after that, if I hover the checkbox, 
it appears.

I am not sure if this will help, but it is the only pattern I could find. I think it 
only happens in a busy environment (lots of open tabs, other programs, etc), but I 
can't replicate it when I want - it just happens randomly :(

It looks like the theory of the GDI handles is on the right way, but I know nothing 
about Win32 programming.

@nsylvain: abortz, one of our former interns, can reproduce this issue on his desktop.  We can run whatever 
experiments you like on it.  Currently he's running with --disable-winsta, but I haven't heard how that's been 
going yet.

@abarth: please let me know if --disable-winsta helps. in theory it should not 
because people started reporting this bug way before the code it changes had been 
introduced, but maybe it's making it worse.

At this point I don't really have more experiments, I just need to start the 
debugger, and trace the win32 calls and find out why they can't paint, and most 
importantly, find out why the control panel is able to map these images back into the 
process. I'm pretty sure the fix is just that we need to hold onto a resource, but we 
just don't know which one yet.

the current theory:
Chrome starts the renderer in the sandbox, which needs the classic theme to be in 
memory. Windows knows who uses the theme and who does not, but since the renderer is 
in the sandbox, it fails to determine that it's using it. When the machine runs out 
of memory, Windows starts cleaning up stuff, including the theme bitmaps, because it 
thinks no one is using it.  Chrome tries to reload the bitmaps, but fail because of 
the sandbox. When task manager is started (or firefox), it caused the memory to be 
mapped again. Moving the cursor on top of the items in chrome will make them repaint, 
this time with the right bitmap.

the browser process should keep these memory regions alive, unfortunately we haven't 
been able to determine yet which regions we are talking about. And we are not sure 
either how to find that out (without having windbg attached to it and spending a 
couple of hours/days debugging it).

I can ask him to install GDB and generate a trace for you.  Is there an easy way to get GDB to generate the trace 
you need?

well, maybe. Can you ask him to install procmon (http://technet.microsoft.com/en-
us/sysinternals/bb896645.aspx) and filter only the chrome process, and see if he is 
getting ACCESS DENIED calls when the page loads. (some ACCESS DENIED might be 
unrelated/expected, if they don't look interesting, we can skip them) If this is the 
case, we can click on the line, and it will show the stack trace of the call.

thanks

Nicolas

I don't know if this is known already - but this bug is perhaps not Chrome specific.
I have a similar problem when installing the Microsoft HPC Pack 2008 RC1. However, 
hovering the radio buttons makes them visible, one-by-one, so it could be a different 
issue.

In chrome 3.0.195.21 this bug is not appeared.

it has appeard for me ( 3.0.195.21 ) and comment #21 is on to something with the 
Windows Task Manager (i think)

a) i always have task manager running in the system tray
b) on a tab not showing checkboxes
c) bring up taskmgr from the systray (taskmgr is set to always on top)
d) checkboxes still missing
e) switch to another tab then back to the offending page
f) checkbox appears!

i will use this workaround for now

It does happen in 3.0.195.21 too.  And VLC seems indeed to trigger this Chrome behavior 
on my machine.  After many months without VLC, I installed VLC 1.0.1 and suddenly the 
arrows on Chrome's scrollbars started to disappear (checkboxes and radio buttons too) 
after watching a movie.  Just as a reminder, I use WinXP SP3 with the classic UI theme.

I've also been plagued by this for a while. I use XP classic theme. If memory serves,
I updated VLC at roughly the time it started playing up. That is to say, my very old
version of VLC did not cause the problem, but the latest version does. I can't
remember the old version number unfortunately.

The most efficient way I could find to fix it was to right click the taskbar and go
to properties. But I'm on firefox until this is fixed.

If you think it's relating to the bitmaps being unloaded when not required and memory 
is low, then run with maxmem=64 in the boot.ini file.

That will limit windows to only using 64mb of ram (windows should just about run like 
that).  That should speed up the issue for debugging.

Also, I guess make sure absolutely no other programs are running, since they might be 
using the same bitmaps, and that might include killing explorer.exe and all other 
processes with a UI.

I suggest it's easier to do this in a fresh virtual machine than mess up your 
development system.

Also, when using process monitor, make sure it is minimised while reproducing the issue 
- that will reduce the number of draws it is doing while updating it's own UI.

i can reproduce this problem with the latest dev release at yahoo fantasy 
football....when you try to add/drop a player. all checkboxes do not show up unless you 
highlight the area, then they appear

checkboxes do also not appear in gmail....

1 - A priority ONE issue - reported October 17th. 2008 - Today is October 4th. 2009.

2 - I downloaded Chrome at first relase

3 - abandonned it because of the akward save-and-reuse of User Id / Password having 
multiple users on the same pc -. Firefox just lists all saved

4 - redownloaded Chrome this week - experienced this checkbox  issue

5  - back to Firefox

6 - wait for solution before return to Chrome

And by the way: why are issues open for updates by morons like myself? We should stay 
in the Forum releasing our worthless opinions.

;-))

I get this as well, but I found a fairly simple "fix".  I resize my window.  The exact 
amount varies, but I usually shrink it horizontally by ~10-20% and the boxes reappear. 

Updated to: 3.0.195.25
Issue still present.

It seems to be intermittent... it rarely works as expected
-

Windows XP, Classic theme.

Yep, I can confirm: a resize will fix it :-?

There must be an overflow in a math calculation somewhere in a component which the 
checkbox component inherits.
Wild guess, I have no idea actually :) But I bet it's a Windows bug... aargh

Version: 4.0.221.6
Windows XP SP3

I notice occasionally, when a page loads, I can briefly see the checkboxes ( less than 
a second ) and then they disappear.

I'm running Windows XP. The first time I noticed this problem was after I tried some of 
the other chrome "themes". My checkboxes and scrollbar arrows would randomly disappear. 
Switching back to the default theme didn't solve the issue.

I propose that we could postpone fixing this until mstone:5.

@jon: This is a really important bug, but unfortunately we don't know how to fix it 
yet. I still haven't been able to replicate on my machine, or find someone who can show 
me the problem live on a machine.

As always, if someone has the problem and knows where I am, please come show it to me.

In 3.0.195.25 this bug is not appeared.

Someone let me use his machine with the problem! (Thanks!) 

I'm still not sure what the problem is, but....

Is there anyone who can replicate the problem easily who does *not* have google 
desktop installed? 

It looks like this could be a bad interaction between chrome and google desktop.

And if you do have google desktop but are not using it, can you try uninstalling it 
and letting us know if it fixes the problem?

Thank you,

Nicolas

I have never had google desktop installed on my machine, and have been experiencing 
this for quite some time.  That said, I haven't seen it in the last, say, month?  
Currently running 3.0.195.25.

I had this problem on a PC where Google desktop wasn't installed.
It probably was a bad interaction with Windows XP classic theme, not the colored one.
I've read many others report this. Actually I'm on another computer, XP, default
colored theme and this prob isn't happening..

I've never had google desktop, yet i have the problem. VLC player seems to be a
common denominator though?

Don't think Google Desktop is involved here either.  But the bug hasn't surfaced since 
my last post here (#160) a few weeks ago, which prompted me to blog about the work-
around I found.  I don't have VLC installed, but I do have a similar program KMPlayer 
installed.  I have not tried any themes either.  I'm up to 3.0.195.25 now as well, and 
like I said it hasn't happened in weeks.  I'm interested if any other people have tried 
my work-around and also have not had it happen to them yet either?

I've had it on two laptops without Google laptops or VLC player. Changed my theme
since, mostly to get rid of this bug.

I see this on a daily basis with a relatively fresh Windows XP install.  Never had 
Google desktop or VLC player installed.  I am using Windows' classic theme.

Me neither. Fresh install, 15 terminals (setup on #144).
No google desktop, same problem.

I still get this bug about once a week on Windows XP with a Classic theme. No Google 
Desktop installation.

I don't have google desktop, and it happens quite often.

Not only do the scrollbars not show up, the radio buttons, and checkboxes disappear.

I also don't have Google Desktop installed, still happened to me. Now running Zune-skin 
to fix the problem :) (temporarily)

Thanks everyone. Looks like this is not a problem with Google Desktop after all.

.. going back to the drawing board ..

More info: This is still happening with the 3.0.195.25.  I just tried the window-resize 
trick which usually works.  This time, it didn't, however, after the resize, I tried 
hovering over the checkboxes in question (in a squirrelmail page) and they reappeared 
one at a time after being hovered over.

 Issue 5176  has been merged into this issue.

 Issue 4866  has been merged into this issue.

@comment 190: they reappear after some kind of trick, so instead of hovering you can
reload the page at that point

same problem with chrome 4.0.222.12
just checkboxes are invisible, but you can still click them (if you know where they 
are, obviously)

http://wps.prenhall.com/esm_mcmurry_chemistry_5/73/18709/4789716.cw/content/index.html
Any quizzes on the above site, as well as webCT can reproduce this problem (to an 
annoying degree).

Comment 9 really helped.

I'm using chrome 4.0.222.12 on a server version of WinXP with the classic style.

A year is gone and this bug is still here.
I cannot use gmail (a Google service) with Chrome (a Google product) beacuse every
checkbox and every radio-button disappear.
This is very funny !
Google is not able to display pages created by Google itself !
Yesterday I restart to use Chrome and TADA....!
... this morning no checkbox displayed by Chrome in any page !
I think that this bug must be resolved ASAP. ASAP! Very ASAP!
In the meantime I will continue to use FF.

I have to agree with dario.  Will this ever be fixed, or is google hoping it will go 
away on its own in Windows 7.  If you're not going to fix it, close the issue as 
"NO PLAN TO FIX" and move on.

I basically have to leave a task manager open on my screen at all times (or switch
to the ugly XP theme) to use Chrome.

How hard can this be to fix?  Sit down and crank on it for 4 days and it will get
done.

> How hard can this be to fix?  Sit down and crank on it for 4 days and it will get

I suspect the fix will be easy once we know what's causing the problem.  As of yet, nsylvain hasn't be able to 
figure it out.  If you'd like to help out, we'd appreciate it.  Otherwise, ranting on this bug thread isn't really 
helping matters.

I have the classic theme, Vista Home 64bit, latest dev version at this time, and have 
no problems like this. However, in Options/Under the hood, when I scroll the scrollbar, 
the checkboxes in the tab flicker. Not all of them at the same rate, and some more than 
the others. Could that be related?

I have the same problem.  v4.0.222.12 on Windows Server 2003.  Obviously, I'm not 
using a theme.

I did a clean reboot, open up Chrome and go to Gmail.  No check-boxes.  I do a google 
search and come to this page and the scrollbar arrows aren't displayed.

As suggested by someone in the thread, I 'restored/maximized' the window and the 
arrows on the scrollbar came back.

I got excited and opened another tab and logged into gmail and . . . NO check-boxes + 
no scrollbar arrows!

I 'restore/maximize' the window and nope . . . doesn't work.

Come back to this page and 'restore/maximize' and nope.

:(  I used to think it was a memory issue . . . now it just is plain wack.

I have nothing open.  Zip, null.  Only 20 processes running taking up 194M memory.

GRRR.

I'm also using (and have been using) the Windows Classic Theme on XP Home SP2 and have 
had this issue today for the first time after using Chrome for many months without a 
problem. I recently installed GIMP and InkScape which also include the GTK (a 
windowing/GUI system). Wondering if that is related.

 Issue 25776  has been merged into this issue.

Hello,

To debug this I'll need the help of some of you.

I created a build with some debugging information, and I would like
to have 2 or 3 people run it and send me the debug log generated.

First of all you need to download dbgview
http://download.sysinternals.com/Files/DebugView.zip

Extract and then run Dbgview.exe

Under "Capture", make sure all items are checked, except "log boot".

Then download my build at http://build.chromium.org/buildbot/bug3543.zip

Unzip it and run "chrome.exe" from it.

If you have Google Chrome installed, don't worry, it won't conflict.

For those who have Chromium installed, you should make sure to close it
first. You may also want to pass --user-data-dir=%temp%\testchromium to
the command line so it does not affect your current profile.

With this build, when a checkbox or radio button is to be painted, it
will add a few lines of debugging information to DebugView.

If you could generate the log for when the checkboxes appears, and generate
the log when the checkboxes don't appear, that would be great.

Try a website with only a few checkboxes, otherwise you might have too much
debug log. http://www.southwest.com (click on Book A Flight) is a good site
to test this.

Thank you,

Nicolas

Included are two logs for when the checkboxes appear, and for when the checkboxes do 
not appear.

A very odd thing that happens is that once I run debugview, the checkboxes will start 
appearing again, but only after I hover my cursor over them.

I will illustrate this in my screenshots.

Thanks to everyone who submitted the log files.

At this point I think i have enough information.

It seems like we ask for the checkbox to be painted correctly, and the OS returns 
success. So in theory it should be painted properly.

The only thing not covered by this test was to see which rect we try to paint. I'll 
most likely do another build with more information about the Rect and see if that 
helps us.

In the mean time, if someone knows how to use spy++, it would be great to see if 
spy++ can see the checkbox. That would tell us if it is in fact invisible, or if the 
size is too small, or the placement is off screen.

Thanks

Nicolas

it is in fact invisible because, if checkbox have title property is set, the text of 
its title is apeared when I move mouse over the place of this checkbox.

And if I click the place of checkbox it change its state to checked.

Displacement wouldn't explain the arrows in the scrollbars to disappear. If you know, 
where to expect the checkboxes and other form-items, they're still click-able.

Hope this helps

(No comment was entered for this change.)

So, I have been having this same problem back and forth on a couple different builds 
and systems.  (On Windows XP, SP2)

If I open a new tab, and then open gmail, none of the check boxes render. If I put 
Chrome in full screen, and alt-tab to another program (say notepad++) and then move 
the mouse over gmail (while notepad++ is in the foreground), the boxes appear.  You 
can also just hit the windows key to bring up the start menu and move the mouse over 
the chrome window to reveal the check boxes.

It is also worth noting that when this happens, I can also use tab to select and 
spacebar to check a check box.  The orange border around the selection is the correct 
size and in the correct location.  The check does not appear when pressing the space 
bar, it stays unrendered.

I meant mention I am running 3.0.195.32 but I have experienced this bug on multiple 
versions of Chrome.

 Issue 9750  has been merged into this issue.

Like comment 202, I also have GIMP installed which further included GTK.

I have never had GIMP installed, you can rule that out as the cause. I don't know what 
GTK is but since I installed inkscape once it maybe could be a factor?

incidentally, this has recently gone way down in frequency for me, it rarely ever 
happens anymore. I've not been using many programs other than my browser so I guess 
that suggests it could be some kind of conflict with another program that causes this.
