I need to be more precise:

• Moving the mouse and moving windows around is smooth, but only after a reconnect

• using the remote mouse:
  The remote mouse can move on the entire remote screen, but it is not visible on the local iPad screen. The local arrow cursor is stuck in the lower half (+/-) of the ipad. It moves correctly to left and right but only proportionally up and down. This happens with any global scale set to > 100%.
  When using a global scale of 100%, the local cursor and the remote mouse match positions - but then the local cursor doesn't go into a small top and a small bottom section of the screen while the remote mouse can go everywhere, still.

• using the local mouse (connected by bluetooth to the ipad):
  The cursor can now be moved everywhere, but the mentioned proportional mismatch still happens in case of global scale > 100%.
