The test URL animates smoothly in Firefox 42. However, it fails to update in latest nightly. When you scroll one of the panes we repaint but not otherwise. This could be a regression from some of the refresh driver interaction I reworked in bug 1195180.
mozregression says this is another regression from bug 1097464.

Tracking in Nightly because regression.
This appears to work OK with the patch from bug 1120784 applied locally.
Sinker, (based on comment 1) bug 1097464 is assigned to you and possibly caused this regression, would you be able to investigate and fix this bug? Thanks!
(In reply to Ryan VanderMeulen [:RyanVM] from comment #3) > This appears to work OK with the patch from bug 1120784 applied locally. This should have been bug 1210784, silly typo. I can confirm that this works correctly on trunk builds including that fix, so I'm duping it over there.
At least, our behavior matches Chrome and older releases of Firefox. Edge has different behavior, but that could just as easily be a bug on their end. Given that our current behavior is consistent with what we used to do and what Chrome does, I think it's still reasonable calling this a dupe.
Given comment 5, I do not think we need to track this bug. Bug 1210784 is already tracked for FF44 so we are good.
Bug 1097464 was backed out from Fx44, which should be available on the beta channel in the next day or so. Fx45+ remain affected, however.
