I have a weird bug which occurs usually after I get my laptop out of sleep mode:
The lock screen is checkered green and red rectangles (my background is visible as the rectangles are somewhat transparent), and after I unlock I get similar squares in some applications, namely the desktop icon labels. I also get a KWin notification:
Which then reappears periodically. The time displayded on the taskbar's digital clock also jumps back to correct time after this notification.
The bug only happens after I use sleep mode, there is no visible problem from start up until I use sleep mode. It started after I used up all my GPU's memory training neural networks.
