I can repro this (on Windows), looks pretty bad. Happens even when keyboard scrolling. There's a bunch of 3D stuff here which I'm not too familiar with. CC'ing botond and matt who might have more knowledge/time to look into this.

Kats, Milan, any thoughts here? Should this be a priority to fix for 55 or do we want to treat it as backlog that would be nice to have fixed someday? We don't have duplicate reports, so I'm not sure how common this issue might be.

Yeah I haven't seen any other reports of this either. Thinker, will you have any time to look into this in the next month or so?

Probably better to let bug 1352442 ride the trains so any fallout from that change has time to be found, given that this is a pretty low-impact bug.

I believe this bug has been fixed only partially. Since the STR are different, I have filed a new bug for this: bug 1360952.
