"Compensation for displays which use overscan is tricky under Wayland, and we haven’t quite got it working yet, so this has been removed for now. The vast majority of displays nowadays don’t need it, but we will be putting it back when we have worked out how best to do it"

So wayland doesn't allow for overscan settings, which sucks because both displays I'd like to use have about 80 pixels that they're not showing.
