I can't repro this on my end, can you share a bit more about your setup?

Comment 3 Davide Cavalca 2023-06-27 09:01:32 UTC 
Ok I managed to get this to repro when booting a 486 VM with S3 video. This looks the same as https://bugzilla.redhat.com/show_bug.cgi?id=2170952 and it boils down to pcem not really supporting wayland. There's some discussion upstream in https://github.com/sarah-walker-pcem/pcem/issues/128 for a related issue. I will push an updated to build forcing pcem to x11 for the time being, in the meantime you can workaround this by setting the SDL_VIDEODRIVER=x11 and GDK_BACKEND=x11 environment variables before running pcem.
