Now we know what the problem is, and it will be gone once qtmir+unity8 start using one surface per display instead of cloning displays as it's currently happening.

While the input subsystem uses the bounding rectangle of all displays. Thus it allows the cursor to move around in (1200x1920) while the only surface is 1080x1920. So there is a dead zone between the display extent and the surface extent. When the cursor hits that area the SurfaceInputDispatcher has no surface underneath, so it decides to not send any further mouse input to Unity8. We can fix that by extending the behaviour of display_input_region.cpp to use the intersection of displays when necessary.
