Public bug reported:
Screen tearing on Firefox when watching a video or scrolling down a
webpage with a lot of text.
Steps to reproduce video screen tearing
1. Open Firefox browser on and go to Youtube
2. Select a video but I recommend a screen tearing video test
3. View the whole video and screen tearing occurs.
Steps to reproduce scroll tearing
1. Open a webpage on Firefox that has a lot of text like a Wiki
2. Scroll down the page and tearing is seen when scrolling
Tried recording the screen with Kazam to illustrate the issue but it
does not record the screen tearing. Tested on Chromium but no screen
tearing
