Description Fedora-user 2023-07-02 09:16:58 UTC 
I dont know what this issue is, it may be hardware related.

After sleeping (no hibernation) and waking my laptop up, sometimes I have a very distorted screen, pixels everywhere.

This often fixes itself, screen goes black and everything works again after some seconds.
