This seems to run pretty well on my retina MBP. We mostly stay around 60fps. There's some bad stuff going on with D2D but that's probably unrelated to the original issue.

Seems like 3 issues here from the profile 1) We're painting an Inactive layer (21% cpu usage). 2) 50% of the time is spent in nsDisplayTableBorderBackground. 3) nsDisplayText::Paint takes a while On Mac, without CSRD, I can't checkerboard much anymore. We checkerboard a lot worse on Gecko 39.

I've been in Amazon a lot in the last week. No slowness here - macbook pro + FIrefox 98.0b6.
Does anyone believe this issue still exists?
