--- Comment #1 from mata  ---
Unsetting the DISPLAY variable is just an easy way to force the fallback for
the graphics driver to be used that's configured in the registry via:

HKCU\Software\Wine\Drivers\Graphics = "x11,wayland"

The way to change the preference order would be to change it to "wayland,x11".

It's really a common theme that applications need to be told whether to target
Wayland or XWayland, since only going by XDG_SESSION_TYPE is not really enough,
and so lots of stuff needs further tweaking, for example this is what I've
accumulated in my .profile:

export QT_QPA_PLATFORM="wayland;xcb"
    export GDK_BACKEND="wayland,x11"
    export SDL_VIDEODRIVER="wayland,x11"
    export MOZ_ENABLE_WAYLAND=1
    export ELECTRON_OZONE_PLATFORM_HINT=auto
    export GVIM_ENABLE_WAYLAND=1

And some of them may actually break wine applicaitons if set, since for example
a windows SDL application running in wine doesn't know what to do with wayland.
Im sure there are more I've just not come across.
