What steps will reproduce the problem? 1. Open www.nbc.com/video/

What is the expected output? Page should be displayed clearly. What do you see instead? Getting black regions on screen.

Note:Attached is the screenshot. This is not 100% reproducible.

Tentatively reassigning to Desktop UI. Looks like a compositor bug - Flash can't itself draw outside of its region.

Doesn't repro on Linux. The page looks fine, no block regions on screen.

Kan thinks it might be a blocker. Have we seen this on other sites?

Repros on Mario 0.14.751.0, so it is already on the Dev channel. Aiming to have a fix for the next Dev release.

we are facing this problem with the specified link only. (Link: www.nbc.com/video/)

I'm not able to reproduce this on 14.0.821.0. Is there any other steps involved other than going to that url?

More info: The spinner on the tab keeps on spinning. And these block sections are two ad areas. Refreshing will load new ads, that sometimes have the black section problems, and sometimes not.

do you have pepper flash on your own builds dave? this might be the difference here

I don't see it in my 826.0 dev build (r92856), which looks like it should be between the version in the original report and in #10. I agree with Zel's line of questioning from #12.

If there's only a single window visible onscreen, the window manager shouldn't be doing any compositing.

Does it repro on linux with flapper?

I'm getting nothing but black on a local news website for my city, and going to www.weatherunderground.com is a truly awful experience. All of the text is garbled-looking, and shrunk down and are mostly black. There is also a lot of "screen tearing" if I try to scroll down both the weatherunderground website, as well as the news website I mentioned above. (Using the latest Dev build on my CR-48)

Not sure what to do here as both these sites render fine for me with every version of chromeos I've tried so far.

Reopened. I think this might be related to https://bugs.webkit.org/show_bug.cgi?id=65131

Fix for https://bugs.webkit.org/show_bug.cgi?id=65131 made it to Chrome in r94086.

Is this fixed/merged to the branch?

Verified in 0.14.811.21 with 14.0.835.23 (r95587). Failed to repro the issue.
