Since starting "mpv" after reboot, again, broke kwin/plasmashell, who knows... I thought of: Settings>Compositor Settings for Desktop Effects untick "allow application to block compositing"
Then "apply" => kwin/plasmashell crash! Then logout: no way to have cursor/mouse pointer with sddm Even after several tty/root/ systemctl restart sddm I had to reboot the computer... Something is rotten in the kingdom of Denmark! I don't know what's coming next, but I thought it was a relevant piece of information.
