Cannot reproduce
Currently running Plasma 6 Wayland with today's git master, 1 screen, with 125% scaling. I do not receive a wayland protocol error but when attempting the reproduction steps twice in a row, I experience a plasmashell crash.
Then that's something else; please report it separately. In fact this specific issue as reported has already been fixed.
