--- Comment #97 from Thomas Lübking <thomas.luebking@gmail.com> ---
As mentioned, there's a workaround in KWin 5.4 and up.
4.x won't see any upstream updates and the patch isn't easy to backport.

The bug is (likely) in the nvidia driver when moving VBOs between system and
video RAM. I have frankly not the least idea how or why that should happen when
locking the screen (except when it's rather "when suspending the screen,
causing a randr event, and the screenlocker is just randomly invoked as well")
