[Mobile Replay - Bug] Video player flickering #74324

Open c298lee opened 4 months ago

c298lee commented 4 months ago

Mobile replays will sometimes flicker. This happens inconsistently and is hard to reproduce. It's been noticed in https://sentry-sdks.sentry.io/replays/f7797884538f49288eccf9497def2634/ at 11 seconds and https://sentry-sdks.sentry.io/replays/f9624587255447bcadd94d913b878d78/ at 15 seconds.

It might be happening due to this fix: https://github.com/getsentry/sentry/pull/74245

@brustolin said it flickers on Safari My experience on Chrome is that it works fine. But might need debugging on Safari

@c298lee will take a look this week on this

Flickering is happening on this replay on Safari: https://brustolin.sentry.io/replays/cbb5f3cfc42240659f4ccdbd19186328/?query=&referrer=%2Freplays%2F&statsPeriod=14d&yAxis=count%28%29

I'm currently unable to look at this on Safari and Firefox since I don't have a yubikey so I can't sign in on super user mode. I've taken a look at other replays in sentry-sdk and haven't noticed the same flickering

I was able to confirm this bug on Safari, however it works fine on Chrome and Firefox
