See Screenshot. The Glitches flicker as you move the Mouse around the Popups' Surface.

Affected are Chrome and Content Popups like e.g. Firefox Button Menu, Bookmark Menu, <select>/<option> Popups.

Disabling D2D e.g. via gfx.direct2d.disabled;true helps.

I'm surprised -not- accelerating causes issues here (as that's what that revision changed!)
We should back out the fix in bug 610713 since it didn't really fix anything for anyone as far as I can tell, and it seems to have caused this. Bas, do you agree?
Bas? :-)

FWIW, I verified my Guess in Comment 0 using HG Bisect against MC:

The first bad revision is:
changeset:   91743:07f55ad76d8f
user:        Robert O'Callahan <>
date:        Tue Apr 10 11:52:50 2012 +1200
summary:     Bug 610713. Disable acceleration in popup widgets to work around Windows/driver bugs. r=bas

The only potential Dupe filed since landing on MC would be Bug 764161, so I don't know if an Uplifting of a Backout to Aurora/Beta would be feasible/justifiable.
I'm fine with backing out bug 610713.

Simple backout. The patch didn't help anything, and it caused this bug, so we should just back it out.
