I believe this is the same bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1640496

@softvision-miralobontiu did you have a video playing on a tab before this?

@jonalmeida yes! I played some videos before this.

I just saw this while testing PiP the other day!
Changed the title to track the real bug better

@mcomella shared a video in #11054 as well:

The video will start looping a few milliseconds of content (audio is fine). Subsequent interactions with the browser will make it unusable (e.g. content is all black) until I swipe it closed.

@softvision-miralobontiu Can you still reproduce this issue with the latest version? We have been unable to reproduce it again (https://bugzilla.mozilla.org/show_bug.cgi?id=1640496 for context)

Hi all!
I was able to reproduce some parts of this issue, following the steps from comment 0, on the latest Nightly build from 6/9 with Google Pixel (Android 10).
The only difference, the tabs don't turn black, they are just frozen, their content doesn't load (reddit.com, instagram.com).
What is curious, that the exact same pages load as expected in private mode.
