This issue no longer happens in M56 Canary 56.0.2907.0 in Win 7, 10, Linux

The revert of Roll OpenH264 from v1.4.1 to v1.6.0 (patchset #5 id:80001 of https://codereview.chromium.org/2440143002/ ) - https://bugs.chromium.org/p/chromium/issues/detail?id=614970#c13 seemed to have fixed this

sprang@ can you confirm that this is expected (based on comment 4)?

Status: Fixed (was: Untriaged)
Yep. I'll do a new roll with updated settings shortly though, just to keep you on your toes.
