Bug ID: 44256
           Summary: Divinity: Original Sin 2: Mouse capture misbehaves
           Product: Wine
           Version: 2.21
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

When the prefix is set to emulate a virtual desktop (winecfg->graphics) and the
game is set to Fullscreen mode (the default), the game captures the mouse, but
it is restricted to the bottom-right corner of the game window, rendering most
of the game window inaccessible via the mouse.

Two workarounds:
- Disabled emulate a virtual desktop
- Change game's display mode to something other than Fullscreen
