It seems to be happening with eos live and installed VM. After loading eos fails to load DE graphical environment only mouse pointer gets loaded. Then I tried ArcoLinux with the same graphic settings and it worked. Might be due to Open GL. Would be grate if a dev could look into it.
Have you tried gnome-boxes? I assume KDE also has a similar app.
Anyway, gnome-boxes is a wrapper around qemu as well, and it is quite easy to use.
I recently tried it, and seems to work well.
I just installed eos BSPWM edition and it worked with 34 enabled. Iām testing KDE as we speak to see if this is got to do with the compositor. Because BSPWM has picom.
If KDE works I will check with Arco Linux XFCE. To see if itās caused by XFCE generally or not.
