On Mac Nightly 2020-03-13, some videos on YouTube are stuttering making the video unwatchable. See attached screen recording of video https://www.youtube.com/watch?v=ubgW1Pdn1-4 The audio seems to playback normally.

Note: with media.av1.enabled=false, the problem is not reproducible.

Current build: https://hg.mozilla.org/mozilla-central/rev/b5c4cdbb59c9ae29f0d60bb45bf70b11fcc1b44a

I can confirm this. I don’t see it with 20200311041149. I do see it with 20200313095322.
