The bug reported here occurs with Nvidia binary drivers 367.35, but can't reproduce it with nouveau/mesa. I tried the official demo version, but it just hangs with a black screen with the OpenGL renderer (unrelated to this regression, occurs with nouveau as well and with older Wine versions).
It may not be entirely unrelated, I'd somewhat expect this to be another instance where mixing OpenGL and D3D causes problems. We may have been getting lucky with the pixel format we selected before commit c92451f295242110bf016facf0e80564f3643d94, and likewise still do on Mesa. If that's the case, +wgl before and after the commit in question may clarify that.
