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...)

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".
