I found some old discussions about this being caused by hostname issues. Here
is my computer's hostname:


nate@Liberator:~$  hostname
Liberator
nate@Liberator:~$  hostnamectl
   Static hostname: Liberator
         Icon name: computer-convertible
           Chassis: convertible

Works fine in X11, it's just broken on Wayland. Also, other Flatpak apps such
as Spectral do run on Wayland. It's just Discord that's broken in this way for
me.
