Looks like this may not be a KDE specific issue as I was able to reproduce it in Gnome. I also think it may be related to another issue I reported as under gnome I was not able to get a double mouse pointer under kernel 6.15.1 without getting the other bug. Image taken with 6.14.6.

Seems like a GPU driver bug if it affects GNOME too.
