With layers forced to be accelerated, the main background on twitter.com is a solid black instead of solid light blue, see attachments.

Accelerated layers makes a huge performance difference in things like BananaBread (25fps to 60fps), and seems to work ok except for this issue.

Hi Alon, does this still reproduce with the latest Firefox?

Twitter changed their background since 2013, so I'm not sure how to test the original issue here. Running with acceleration on for a while, I didn't see anything else similar either on other sites.
