No Peter, this is incorrect. Wayland is just fine with programs running
as root. The bug is in gdm3 which is supposed to generate an Xorg
configuration that sets up XAUTHORITY. Instead when it configures the
Xwayland X11 compatibility server, it configures it to check UID instead
of using XAUTHORITY. The result is that X11 apps running as root fail
to work, but native Wayland/GTK3 applications run as root work just fine.
