Title:
  Moving windows between monitors with different scaling causes isues

Status in mutter package in Ubuntu:
  Incomplete

Bug description:
  When two displays are connected and one has a 200% scaling, moving
  apps between them results in several issues:

  Apps that can actively scale (such as native Nautilus, Settings...):

   When dragging the window around, it automatically adjusts scaling
  based on on which of the monitors is the majority of the app (this is
  probably correct behaviour),

  BUT when using keyboard shortcuts [Ctrl] + [Super] + ←/↑/↓/→,
  fullscreen windows jump around and scale correctly, but half-full
  screen apps (arranged by [Super] + ←/→) cannot go from the larger
  monitor to the smaller, they get stuck in the scaled-up version and
  don't fit on the smaller display.

  Small non-maximized windows don't have this issue, possibly because
  when they first move in their scaled-up state, they do fit on the
  smaller monitor still, and only then are they scaled down.

  
  Apps that don't support changes in scaling and only apply the new scaling on 
a relaunch (such as Chrome) don't have these issues, but they obviously have 
that other problem.

  
  Description:  Ubuntu 20.04.4 LTS
  Release:      20.04
  mutter 3.36.9

  What I expect:
  Windows covering half a full screen, when moved to a different display with 
different scaling (using a keyboard), stay covering half a full screen.

  What happens instead:
  When moved to a display with higher scaling, this happens correctly, but when 
moved to a monitor with lower scaling, they get "stuck" on both monitors in 
their inflated state.
