Not major. http://bugs.winehq.org/page.cgi?id=fields.html#importance
"major Major loss of functionality for a wide range of applications"
Fits quite to the profile.
Have you tried to disable "UseGLSL" in Regedit ? I know that this problem exist in Wine Linux too, see #26562
That stuff I always try first, but when doing so the game won't launch anymore ;)
