I can't say this way what the problem is. Is the game using OpenGL? If so run using WINEDEBUG=+wgl and attach the log.
Yep, the game engine was using OpenGL. It's also possible to switch it into D3D mode, but I didn't think about that while testing. I think I give D3D mode a try, maybe the problem does not appear there.
I can create a debug log in a few hours. Going to ask Jan if he's able to do it (faster this way). Also Jan wanted to do his own bisect, so he could verify the faulty commit I found (maybe I did a mistake while bisecting? But I'm pretty sure I did NOT...)
In short I don't understand why this patch would cause issues. For years wine's opengl has been limited to the use of 1 pixel format. As of the patch this limitation was lifted (because Alexandre fixed the parts which caused the limitation). The patch adds dozens of more pixel formats which should make games a lot happier.
Frankly I was expecting the wgl aux buffers commit to pop up, or something related to front/back buffer stuff.
Gonna report back as soon as the log is done. I also gonna check if the visual error appears with the "First Encounter".
