What steps will reproduce the problem?
Mac Chromium 6.0.477.0 (Developer Build 53676)

I don't have repro steps, but I've been seeing this a lot since I updated my copy of Chromium. Tables are being rendered incorrectly, with a cell's size being blown out. Reloading the page seems to fix it. I've attached 3 sample screen shots.

What is the expected output? What do you see instead?

http://trac.webkit.org/changeset/63994 could be the problem.
("Updated table painting to draw cell layers in the correct order.")

After reload, it can be fine sometimes but also can stay bad

This patch should fix this issue.

Having similar issue, but refresh doesn't seem to fix anything for me. It just seems to to display another cell incorrectly.

The issue the chunk of the render tree that is constructed before layout is non-deterministic. If the entire render tree is constructed before layout, then things will be fine. If not, things will be broken. I did not take this into account when I initially patched table rendering in webkit  bug 40775 . The patch I posted for webkit bug 42993 addresses this issue.

It appears the same bug I filled here:
https://code.google.com/p/chromium/issues/detail?id=50353

I did a little investigation, and it seems the things changed between 53616 and 53619 builds.

At first only vbulletin forums seemed affected, then I noticed the same layout corruption in other pages, even in code.google.com 

I confirm that a refresh doesn't fix anything.

I don't think the fix has actually landed yet into WebKit.

This is a bad regression. Happens on Windows also with every page. reload fixes the problem.

#27 thaumb...@windstream.net
Just exactly when is this fix actually going to land and be included?
Build 54025 is still exhibiting the problem. I wouldn't mind so much except that it's getting tiresome to have half a screen of white space in my webmail account, and having to scroll way to the right and at other times having to deal with a column about 150 pixels wide because the content of tables is so badly skewed.

I apologize for the above comment #27, it looks like in build 54086 the table fix is in and working.

seems to be fixed in chromium build 54084
