This one could be relevant. It's plain Android UI code, not MAUI, but I get the same problem in MAUI.

It is very obvious that half the border stroke is clipped when using CornerRadius such that the border becomes circular. It can be combatted using Padding. But something has changed in MAUI and ImageButton.Padding doesn't do anything. Seems like its not applied anymore.

@espenrl the padding fix was just merged #22364

That's super @mattleibow Perhaps ImageButton could have been coded such that it dealt with the issue of clipping half of the borders?
