This bug is NOT fixed on the Radeon FOSS drivers (see comments: https://appdb.winehq.org/objectManager. php?sClass=version&iId=30403&iTestingId=87553 ). I still get "FATAL ERROR: wglCreateContextAttribsARB failed".
That sounds like a different bug.
Given that apparently it fails in wglCreateContextAttribsARB for you on Mesa drivers, it's possible the game wants to create a GL 3.2+ compatibility context. If that's actually the case there isn't much we can do.
Anyway, if you want to go deeper into that, please open a new bug attaching a +tid,+wgl trace.
