Public bug reported:
On Ubuntu 20.10 x64 frequently updated.
I noticed in the last week that after a while there are huge screen
artefacts, that I would describe as flashing. Squares of screen flash,
normally linked to widgets on screen.
E.g.: the app bars on the left can start flashing blue, or parts of editors.
I noticed it more in firefox, made worse by scrolling.
VirtualBox is severely affected too.
VS Code.
It does not happen immediately and the feeling I get is that it starts
happening when there is a lot on screen. For example has not happened at
all in this session, but I have done little or nothing screen-heavy.
The issue gets worse, then might settle down for a while.
