I tried creating an XR scene, however for some reason it gets moved to the top of the screen, as you can see in the image. The gray box below the scene is the place where the canvas is supposed to be. Why is that and can I prevent this?
that would probably be the expected behavior. the emulator is for development purposes. when in XR you can turn on spectator mode if you wish, but otherwise - the canvas is not being updated in any way.
