Build ID: 20130215130331

Steps to reproduce:

Tried to use RSS feeds and the search suggestion menu


Actual results:

Both menus only actually appear / render a fraction of the time. The rest of the time the shadow effect below and to the right of the menu appears, but nothing appears where the actual menu is supposed to be. Clicking on this space still follows the link, so the menu is still there, but it's not visible.


Expected results:

The menu should have rendered properly
I'm pretty sure there is already a bug about this issue.

Could you try with HWA disabled in Firefox, please.
See https://support.mozilla.org/en-US/kb/forum-response-disable-hardware-acceleration (restart FF to apply)

If disabling HWA fixes the issue, paste the section "graphics" from about:support.
Flags: needinfo?(haordslp)
Are you using multiple displays?

I got this very same problem AFTER disabling HWA.
In fact, I disabled HWA in order to fix character rendering and then I got this problem.

Solved this way

Set gfx.content.azure.enabled to false
Set gfx.direct2d.disabled to true
Set gfx.content.azure.backends to Cairo

Especially the last one fixed the "shadow only" menus.
Looks like an Azure issue therefore.

Nope, I still get this problem from time to time, just less frequently, for some reason.
I think bug 872466 is similar to yours and the issue appears with HWA disabled.
in the comment https://bugzilla.mozilla.org/show_bug.cgi?id=872466#c2 a user found a regression range.

Could you use the same tool mozregression (see http://harthur.github.io/mozregression/) to find the same regression range.

Avast! warned me about a possible threat in find.exe
I downloaded again from
http://mozilla.github.io/mozregression/
And I got the same warning
So I reported it as a false positive

I'll try to use it anyway.

Yes, Avast is the king of false positives, of course this application is safe and used by many Moz devs and bug triagers.
Does this still reproduce with current versions?

Can't reproduce on v 41.0.2 and hasn't been an issue for some time now.
I think this was related to Bug 812695
