Title:
  cursor does not track window when dragging between monitors with
  different scaling factors

Status in Mutter:
  Fix Released
Status in mutter package in Ubuntu:
  Fix Released
Status in mutter source package in Lunar:
  Fix Released

Bug description:
  Impact
  -------
  I have two screens. My laptop is using 200% scaling and the other external 
screen is using 100% scaling. When I drag windows between the monitors the 
cursor moves to unexpected locations when it moves onto another screen with a 
different scaling factor.

  I would expect the cursor to stay in the relative location when I
  started dragging the window. Hopefully this is clear the the attached
  screencast.

  Test Case
  ---------
  1. Install the update
  2. Log out
  3. Log back in
  4. If not already done, open the Settings app. Click one of the displays in 
the list and set it to 200%. Leave your other display at 100%.
  5. Drag a window from one screen to the other.
  The cursor and window should smoothly transition from one displays to the 
other without the cursor jumping dramatically to a different location when it 
crosses between the displays.

  Other Info
  ----------
  Setting different scaling for different displays requires Wayland. This will 
not work with the Ubuntu on Xorg session.
