I'm closing this bug then, thanks.

If you're running Wayland, then it's a limitation of the Wayland
protocol, which has no global coordinate system.  GTK exposes it as
every Wayland window (surface) being placed at 0, 0.

On Emacs compiled with pgtk, (frame-parameter nil 'fullscreen) returns
nil when the frame is maximized.  (Without pgtk, it returns the symbol
'maximized'; if I make the frame fullscreen, then the above always
returns the usual 'fullboth'.)

I'm using Gnome on Wayland.  More system information below:
