Bug Description
Using firefox on the 18.04 default session (gnome-shell on Xorg) I get screen tearing when scrolling and also in videos. It's evident in this video for example:
https:/
Where the lines between white and black areas seem to jump around and that's not visible in a screenshot.
When scrolling it's common to see horizontal discontinuities in the text.
Here's the details of my graphics card:
