There are similar topics in the bug lists, but I think the one with the shadow has been deleted. Don’t feel like looking.
But I think the double mouse cursor and reflections are still there. The funny thing is that these bugs and worldscale would probably all be fixed if they incorporated Wide FOV. At least that’s how it was in most other applications.
It’s possible that it’s a bit more difficult in openXR.
Funny questions abound on the Khronos forums. But I can’t see through it anyway.
