New info of a chat with a KWin developer:

The problem started after "Direct Scanout" was implemented in KDE Plasma 5.27
released on 2023-02-14.

Workaround: One can disable the "Direct Scanout" using the environment variable
"KWIN_DRM_NO_DIRECT_SCANOUT=1" in /etc/environment and relogging / restarting
the computer. The problem should go away.

I just discovered, that it does not only occur in Firefox but other
applications too and seems to be a general problem of KWin, therefore I changed
the ticket title. It also happens on Signal. To reproduce it there send a video
into a chat and start playback of it, enter fullscreen playback and move the
mouse. You see the same glitches and mouse cursor size changes as in Firefox
playing a YouTube video.
