Description Alexey Proskuryakov 2020-12-28 12:59:47 PST
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.

Added a flaky expectation in http://trac.webkit.org/r271104

Does not seem to have helped much on the bots :(
Comment 7 Antoine Quint 2021-04-08 05:36:54 PDT
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.
Comment 8 Alexey Proskuryakov 2021-04-08 10:19:22 PDT
On the bots, I see flakiness in all configurations, but mostly on release, ASan and GuardMalloc - failures in debug are rare.
Comment 9 Antoine Quint 2021-04-09 08:54:59 PDT
I'll be addressing this in bug 224066.
