Black Box Bug Part 2

Remember when I made that post about the black box in the corner?https://wilds.userecho.com/topics/3608-black-box-bug/

Well, turns out it moves! If you press the fullscreen button it goes into the corner and becomes very obnoxious. Going out of fullscreen mode makes the box go back to the corner and using a different method to go fullscreen doesn't make the box moves.
