Bug ID: 57303
           Summary: KnightOfKnights broken in "fullscreen" on wayland
           Product: Wine
           Version: 9.19
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The game only supports fullscreen with 800x600.
On X11 the screen switches to fullscreen 800x600 and works normally.
On wayland (both winex11 and winewayland) the window has the size of the
monitor (in my case 4k), but the menu only renders in the very top left 800x600
pixels.
Once the 3d scene starts, it scales up to 4k, but looks very broken.

To test:
- Download the game
- winetricks -q directmusic d3drm d3dxof gmdls
- winecfg -> Enable virtual desktop
- Unplug gamepad
- Start game, press z/y depending on your keyboard to confirm
- In "Stage Select" move left, then confirm. After character select it enters
the 3d scene
