In the past few nightly builds, I've been seeing black bars seemingly randomly appear while scrolling various web pages. If I scroll them offscreen and then scroll back, they are gone. See attached. Nightly 39.0a1 (2015-03-20) OSX 10.8.5 Intel HD 400 + NVIDIA 650M
Not sure if dupe of https://bugzilla.mozilla.org/show_bug.cgi?id=654570 but I've been using Nightly for quite some time without this issue, and seems to be new as of this week? That bug seems pretty old (reported 4 years ago).

I recently upgraded to OSX 10.10.2 and saw this again. FF 40.0a1 (2015-03-30)
These were gray. When scrolled off screen, they disappear. When I mouse over a link triggering a paint, the repainted area is fixed but not the entire gray box. When I slowly start scrolling the box off screen, it disappeared before it was completely off screen.
Comment 3 was OSX 10.10.3 FF 38.0.1.
chrome content messed up in top right hand side
I'm starting to see this in production FF 40.0 OSX 10.10.5. Note: I'm on a new MBP, since my old one is getting fixed up. Same hardware. NVIDIA GeForce GT 650M OpenGL Engine 1024MB
moving over the black area with my cursor does not repaint, only scrolling the black bar off the page seems to repaint correctly.
