            Bug ID: 57840
           Summary: Discworld Noir - half Screen and wrong colors
           Product: Wine
           Version: 10.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

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.

This palette weirdness also happens on modern windows when running the game in
a window instead of full screen. In your game settings, is it set to window or
full screen?

I have been running Discworld Noir in wine by using winecfg to "Emulate a
virtual desktop", then I run the game set to full screen.

More details about this issue in this video attempting to get the game running
in Win11 at https://www.youtube.com/watch?v=PKlOCMjaGdc&t=608s
> From what I gather, internally it's got hardcoded 16-bit colour going on?
> If you don't want to run in an emulated virtual desktop, you can instead
> attempt his fix at https://github.com/nathan-baggs/dolomite if you know how to
> build it.
