Screenshot of game with broken colors

When running Discworld Noir with an unmodified wine-10.0, the game works, but
the colors are messed up and the "resolution" is broken. (See the attached
images)

It is possible to run the game with xephyr (Xephyr -br -ac -noreset -screen
960x600x16 :4) in a lower color mode, which fixes the issues. It seems 32-bit
color causes issues with the game.

Sadly, xepyhr is not available on all platforms.

I am not sure if this is even fixable by wine itself, so feel free to close
this issue if it is not applicable.
