--- Comment #6 from Béla Gyebrószki gyebro69@gmail.com --- Does it help if you disable CSMT? (winetricks csmt=off)
I think I managed to reproduced the problem on Nvidia and in 32-bit color depth, using the following setup: Gothic 1.08k + Player Kit v1.08 + Gothic 1 SystemPack v1.7.
My former test was done with only the base game installed (Gothic 1.08k from GOG.com), it seems the problem arises when the community made System Pack is installed. Disabling CSMT fixes the issue for me. The problem exists with mesa 17.3.7/nouveau too.
