@sleve_mcdichael I've done this when I first started using overlays. I've found it works with some, not with others. Depends on where the overlay is from.. and if I decide to zoom in or zoom it out a little. I try to set my overlays/bezels to the best possible screen size for the system, and that's not always the stock size.
I eventually switched to manually setting the size and it seems to work really well . Once I'm happy with the bezel, I don't change it anyway.
BTW... Your description is probably the best I've read on the subject. Thanks for sharing it.
