I've been using Fences for at least a decade. Up until recently (I think it was when I finally went to Windows 10 20H2, I skipped 2004 and maybe 1909) desktop icons ALWAYS wrapped around a fence. New or existing. As soon as a program installed, the icon popped up to the right of the upper left fence and scooted everything else over, never under a fence and invisible which is definitely the case now.
Any time you dragged a fence to a different location, the icons on the desktop always moved out from under them, but that doesn't work anymore either. I know MSFT created the problem, but it would be awesome to see it working again if possible.
