Public bug reported: On a dual/multi monitor setup, if the monitor adjacent uses a different scale factor, when moving an application window to the boundary the application will change its scaling just slightly before the actual apparent window starts crossing over. Taking a look at looking glass shows the transition occurs when the MetaSurfaceActorWayland region (larger than the actual window) meets the boundary.
