The following 7 webrtc tests are flakey timeouts in BigSur Debug wk2 on Apple Silicon only: webrtc/video-rotation-no-cvo.html webrtc/video-rotation.html webrtc/video-setDirection.html webrtc/video-sframe.html webrtc/video-unmute.html webrtc/video-with-data-channel.html webrtc/video.html HISTORY URL: https://results.webkit.org/?suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&test=webrtc%2Fvideo-rotation-no-cvo.html&test=webrtc%2Fvideo-rotation.html&test=webrtc%2Fvideo-setDirection.html&test=webrtc%2Fvideo-sframe.html&test=webrtc%2Fvideo-unmute.html&test=webrtc%2Fvideo-with-data-channel.html&test=webrtc%2Fvideo.html&architecture=arm64 All of these tests have very similar histories in the sense that they all started flakey timing out when they started to run on Debug on Apple Silicon Macs. It should be noted that the timeouts are flakey, but they occur more often than not.

Created attachment 422940 [details] Timeout diffs Attaching all 7 diffs for the tests that are timing out.
I cannot reproduce these failures because they only occur in Debug on Apple Silicon Macs, and I do not have access to one of those systems.
