I quickly tested all of the flatpaks here and they seemed to work. org.gnome.Chess and org.gnome.Extensions are complaining about DRI2 access but seem to work fine otherwise:

libEGL warning: DRI2: failed to authenticate Gsk-Message: 23:24:28.651: Failed to realize renderer of type 'GskNglRenderer' for surface 'GdkX11Toplevel': Unable to create a GL context

Passes quick smoke testing.
