Cannot scale-to-fit mumble
The preferences window in Mumble overflows a lot.
p-m-s does not show a separate entry in the compositor panel.
It was previously suspected that the problem being that it's run through xwayland where scaling does not work,
however I've verified that it runs indeed under wayland (WAYLAND_DEBUG=1
works).
See this video (with ~13MB too big to attach to gitlab directly):

I will check wayland logs for what type of surface is being opened for the preferences window, but I wanted to share my initial findings already (so I won't forget to do it later).
