WINEDEBUG=warn+all output

Many games fail to produce a fullscreen image when launched on Wayland. The
image is shrunk into the corner with the rest of the screen black, instead of
stretching it out. Some games don't fill the rest of the screen with anything
and you can see the desktop.

Games affected are Starcraft Brood War, Airport Mania First Flight, Ricochet
Lost Worlds and others. A small indie game called Cave Days also throws the
error "Only windowed mode is supported" on Xwayland but works fine on X11.

Please feel free to close this report if this is expected behavior in XWayland
for now but all these games work fine on X11.

I've attached a WINEDEBUG=warn+all log for Starcraft.
