I saw in another bug that it already got backported in a PPA by Mario
Limonciello: https://launchpad.net/~superm1/+archive/ubuntu/lp1928393
However the bug manifestation looks different in that bug:

Since the situation was unbearable, as I didn't want to sit with a

was introduced that now causes intermittent freezes. See the new bug:

Additional info and observations:
- Sometimes there is also flickering in videos (for example zoom
calls), without freezing
- The flickering and freezes seem to be less (but not entirely
removed!) when using a lower refresh rate
- While I am using the mouse, no flickering will occur, as soon

continues to work. There is absolutely nothing logged in
