1087545 - Scrolling only updates top few pixels of content

Status: RESOLVED DUPLICATE of bug 1087257

Description

[Sean Stangl [:sstangl]]

Today's Nightly (10-22-2014) is unusable on my system: mouse scrolling on any page only appears to update the top 30-or-so pixels of the content. The rest of the content does not update. Occurs independent of e10s.

I attempted to take a screenshot of the problem, but pressing Alt+Print Screen apparently causes the page to fix the rendering problem right before the screenshot is taken.

I took a low-quality video that shows the problem on planet.mozilla.org and hosted it here: http://people.mozilla.org/~sstangl/screencast.ogg

(I was able to work around locally by disabling e10s *and* turning off "layers.offmainthreadcomposition.enabled", FWIW.)
