Bug ID: 57728
           Summary: Sensitivity of relative mouse movement is scaled by
                    coefficient of desktop scaling
           Product: Wine
           Version: 10.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winewayland

I am using GNOME Wayland session with main monitor (1440p) running at 125%
desktop scale.

Currently there's a bug with application scaling being done separately based on
DPI value, so I set DPI to 120

In all first person games the same mouse travel distance leads to a higher
camera rotation angle in game.

So if a game has a sensitivity slider, to get the same mouse sensitivity as you
had at 100% scale, you need to divide this value by your desktop scale (in this
case, 1.25) and apply changes to these settings on per-game basis. Obviously,
not an ideal workaround and requires to do a lot of tweaking.
