STR:
1. Enable webrender
2. Open some video (Youtube etc...)
3. Scroll the page

Expected results
Video shows normally any time.

Actual results
(In my case) Left side of video didn't show and clipping area moves while scrolling.

Regression range
autoland

So, caused by Bug 1503447.

Interestingly, in my PC, this problem happens only 64bit version.

I see this on Reddit pretty easily too.
Actually, I think this should block the Beta65 study rollout.
If I open https://old.reddit.com/r/AnimalsBeingBros/comments/a1gyif/cat_high_fives_runners/, the autoplaying video goes black almost immediately after it starts playing. Reproduces on both 32-bit and 64-bit builds.
We should probably back out the patches from bug 1503447 that are relevant here (1e214baf8fc1 + followups 7d4adeee5236 and f5ffebdcc014)

Back out some commits from bug 1503447 for introducing correctness and perf regressions. r=backout
It would be good to add reftests covering this, if we want the changes to re-land at some point.
Thanks for backout!
