Noticed this for the first time a few days ago on Nightly. Whenever I use a doorhanger notification I see graphical glitches in particular with the buttons in the bottom right of them. They often end up not rendering, and the content beneath is rendered instead. I couldn't take a screenshot of this for some reason, but here's a photo of the issue: https://people.mozilla.org/~bhearsum/sattap/IMG_20131008_114350.jpg

Hmm, I'd suspect a gfx bug. Is this just an occasional glitch, or does it happen reliably? (ie, how hard would it be to narrow down a regression range?) Does turning off hwaccel help?

100% reproducible. I'll try to bisect against nightlies this week, shouldn't be terribly hard to.

Why is this blocking b2g? It only affects linux afaik. I think this is just a dupe of bug 923542.

Cool! Closing this bug then.
