Description Said Abou-Hallawa 2021-02-19 11:53:49 PST
PaintTiming causes about 4% regression in the MotionMark sub-tests: Multiply and Focus. Do disable it for now.

I believe that the root cause is fixed here: https://trac.webkit.org/changeset/273220/webkit

I don't have the means to test the effect on MotionMark result, as locally it doesn't produce consistent results for me.

Said, Can you or someone else with access to the consistent testing environment help make sure that this is true and perhaps revert this patch?
