Build ID: Mozilla/5.0 (X11; Linux x86_64; rv:39.0) Gecko/20100101 Firefox/39.0 ID:20150320030211 CSet: 4d2d97b3ba34
Arch linux on thinkpad x230, using intel graphics, X11, kwin with compositor using OpenGL 3.1

I started noticing this bug yesterday, on both gmail and hulu. I don't have reliable STR at this point, but it has happened twice.

I will get a completely black content area (chrome continues to render fine). Anything that causes individual elements to repaint will lead only to that element being drawn. Something that requires a full repaint, like scrolling or switching tabs will restore the correct content.

Attached is gmail after hovering over a few elements.

Once a full repaint has occurred, the bug does not manifest again, at least in the timespan I have observed

Another one on relayrides.com, so I don't think this is related to websites.
