I saw a theory that this could be a dupe of bug 217851. Is this still happening, with that bug now fixed?
So for the tests: webanimations/accelerated-transform-related-animation-property-order.html webanimations/accelerated-translate-animation-additional-animation-added-in-flight.html webanimations/accelerated-translate-animation-underlying-transform-changed-in-flight.html webanimations/accelerated-translate-animation-with-transform.html webanimations/accelerated-translate-animation.html There hasn't been a failure on iOS since r268735, which predates the fix for bug 217851, which is r268746. My guess is that r268746 does indeed fix this, but the bots started passing before that because of when they had been last rebooted. Indeed, the underlying cause was the up-time of the machine relative to times used in animation tests. We would have to reboot those bots to know for sure. I'll let Hector or anyone else on the bot watching team decide what to do with this bug.
Verified no failures since r268741
