plain terminal output

Most objects (trees, buildings, people) are pitch black in Black & White and in
the Creature Isle expansion.
Changing graphical details in the setup menu or disabling GLSL, CSMT don't make
a difference.
Reproduced the problem with nouveau/Mesa 19.0.0. and with Nvidia binary drivers
418.49.04.
There is no demo version available. Please let me know if you need debug logs.

I found that the problem is present since commit
961a94ac046644004718c56bfeeb81740cb73793.
I couldn't revert the commit on current git, but I verified that textures are
rendered properly with the previous commit.

Still present in wine-4.4-188-gc988910cae (also in Staging).
