Updated test expectations at https://trac.webkit.org/changeset/281962/webkit.
Comment 3 Kimmo Kinnunen 2021-09-08 12:02:21 PDT
I believe the root of the problem is partially that the WebGL video tests are hanging or crashing due to bug(s) in platform components. At least some have been identified and fixed, but it takes time to get them released.
