Comment 2 ayumi_kojima 2021-09-10 14:55:54 PDT

I was not able to reproduce the timeout locally on Catalina using: run-webkit-tests --iterations 1000 --clobber-old-results compositing/video/video-object-position.html -f --force

Comment 3 ayumi_kojima 2021-09-10 15:08:33 PDT

It seems like the test is not flaky anymore on EWS. Closing the bug.
