Observed: The centre point of the map display control area is not the centre point of the map screen. The causes issues when using ctrlMapScreenToWorld, as [0.5, 0.5] is the center of the screen, not the display control.
Expected: Both the map display and map screen centre should be the same point, as was the case in Arma2OA. Alternatively, the control centre could be moved to the display area centre, but this point is not the centre of the screen.
My terminology might be a bit off, hopefully this makes some sense. {F22760} {F22761}
