Could you make a try with HWA disabled to know if you're able to reproduce it, please.

Same results with HWA disabled
Milan, is this a dupe of bug 1040187 ? If so, can we get the relevant patch(es) uplifted to 33, perhaps? :-(
Flags: needinfo?(milan)
It is possible, but bug 1040187 was going away with HWA disabled, where this one is not.  We don't have that fix at Beta yet, but we do have it on Nightly and Aurora.  Mike - we appreciate all the help you've been giving us in tracing this - any chance you can try with Firefox Aurora and see if the problem goes away?

Downloading now.  For what it's worth, the icon looks cool.  I'll let you know shortly.

So maybe this may be my bad.  I use WindowBlinds and when I first saw the issue, I told Windowblinds to exclude firefox from being skinned.  As I hadn't changed or updated Windowblinds, I assumed it was something with Firefox.  I tried a couple other things and it was still occurring, however I hadn't tried completely unloading Windowblinds.  With Windowblinds completly unloaded, both Firefox and Aurora work fine.  With Windowblinds enabled, Aurora works fine, but Firefox has the graphical issue still.

Did you see these graphic glitches with the previous versions of Firefox?

No, it started with this version.

Maybe a possible regression in the code of FF32.

As you are able to reproduce the issue on your machine, could you install the tool mozregression (see http://mozilla.github.io/mozregression/ for details) and post here the regression range you find (console output)?
Be sure each Nightly downloaded and launched by mozregression is not excluded from Windowblinds.
FF32 nightlies started in May 2014 (2014-05-01).

No more inbounds to bisect

First bad revision: 4623a4cfe024

Also note, I've found that the issue only occurs when the window is maximized.  When it's not it works fine, even with the current version of Firefox.

Thanks for the regression range, it's helpful.

I believe the suspected bug is:
