When I play a video in fullscreen with firefox (i.e. youtube, netflix etc.) it tears constantly. Chrome, Chromium and Opera don't have this problem. How can I fix it?

If you are certain the issue is with Firefox and it is not system wide then the following may solve your issue.

Type "about:config" (without quotes) in your address bar in firefox, click accept if prompted and then search for layers.acceleration.force-enabled. Double click the search result to turn the value to true.

Now restart firefox and the issue should be solved.

  • Thanks! but now why wouldn't watching netflix "enable" acceleration by default?

I had same issue in 20.10, but layers.acceleration.force-enabled = true alone doesn't worked for me. Here is an approach that finally worked for me. https://askubuntu.com/a/1288650/975640
