--- Comment #3 from Matteo Bruni matteo.mystral@gmail.com --- Okay, let's try to clear up these bugs.
(In reply to multitude from comment #2)
From https://bugs.winehq.org/show_bug.cgi?id=37838 does it look like the 'Chessmaster X with OpenGL' or 'Chessmaster X with Direct3D' attachment?
It does look like 'Chessmaster X with Direct3D' for me, which is what it looked like before the regression caused by 9811d85141610f903d6c8de3b00be6c853ece182 (wine 1.7.39).
Is Chessmaster running in Direct3D render mode? You can configure it via 'cmsettings.exe'.
Direct3D.
So AFAICS the patch you mention actually fixes a regression (that is the broken lighting from attachment 51137) and I don't see any new regression compared to wine 1.7.38.
The issue bug 37838 was originally about is probably still there instead, but I'll comment on that bug in that regard.
