That's an interesting point. You potentially also have alignment issues with the window being placed spatially, i.e., rendering text that is not perpendicular to the plane of the screens. When moving my head in the AVP I'm moving the screens, unlike when I move my head to look at a different part of a monitor.

Yeah with slanted screens it might well be best to not align anything, at least beyond certain angles
