--- Comment #25 from Jan Seiffert kaffeemonster@googlemail.com --- This bug also affects Capitalism Lab, Enlights continuation of the Capitalism series. Prop. because it is still the same graphics engine, they are "just" extending the simulation (Latest DLC "Banking and Finance" from 2020, latest exe 8.0.13 has a 2022 copyright).
I tried wine-6.23-staging, wine-7.1-staging, wine-7.2-staging, same graphics glitch, no redraw of the map, except where you move your mouse courser. wine-7.0-tkg also has this graphic glitch, but game-voice output is working, yeah?
I found the following forum entry: https://forum.winehq.org/viewtopic.php?t=31396#p136066
And yes, when you: 1) switch OffscreenRendering to "backbuffer" and 2) run the game fullscreen
the map is drawn. Problem is, for me, it fullscreen flickers like hell.
This all smells like a bug between ddraw4/fbo and the game/Wine? probably in error specifying DISCARD semantics, skirting some undefined behaviour in windows where it is actually getting COPY semantics. (please have a look at https://bugs.winehq.org/show_bug.cgi?id=3467, this game apparently uses a funky AddAttachedSurface which is only possible with ddraw4, ddraw7 disallowing this/only allowing Z_Buffer surfaces)
