webanimations/accelerated-animation-with-easing.html used to pass reliably on Mac (not on Linux), but it's become flaky on Debug starting 2020-10-23. First failure observed on r268941. The closest animations related change before that was http://trac.webkit.org/r268932. History: https://results.webkit.org/?suite=layout-tests&test=webanimations%2Faccelerated-animation-with-easing.html The diff is an image, there is a thick red line on actual image.

Does not seem to have helped much on the bots :(

This used to reproduce the issue reliably: rwt --debug --iterations=10000 --force --exit-after-n-failures=1 --no-build webanimations/accelerated-animation-with-easing.html … but doesn't anymore.

On the bots, I see flakiness in all configurations, but mostly on release, ASan and GuardMalloc - failures in debug are rare.
