Output stretched when not in fullscreen

[riderodd]

Hey there,

Firstly thanks for your amazing work! I'm really enjoying SceneView :)

I've found a bug on render with ArSceneView when the dimensions of the view is less than full screen height, and camera permission hasn't been granted. The output is stretched like that:

When I run the app again it works fine:

It's really linked to the permission dialog. If I close the app, remove the camera permission, and run again, the bug appears again.
