This could be one of a number of bugs.
If you are using the old 'intel' driver then it's bug 1867668.
If you are using multiple monitors then it's bug 1853094.
If you are using fullscreen apps then it's bug 1754284.
If none of the above then this should probably move to the window
manager ("marco"?).
** Package changed: xorg-server (Ubuntu) => marco (Ubuntu)
** Summary changed:
- Ubuntu 20.04 screen tearing intel graphics
+ MATE desktop in Ubuntu 20.04 screen tearing intel graphics
