Gregory's Server@lina It's also worth noting that this is Kodi's X11 backend (inside Xwayland), still having some troubles starting the Wayland backend for a change. Usually it's the other way around...
Hopefully there's just some silly bug and we'll have All The Windowing Systems working for Kodi.
mpv works with both X11 and Wayland, at least.
@alyssa @lina that's very cool - considering Kodis history; originally being XBMC, I can imagine the way it's written might be a bit different to other apps.
