--- Comment #4 from Rico kgbricola@web.de 2013-01-20 08:58:59 CST --- Created attachment 43253 --> http://bugs.winehq.org/attachment.cgi?id=43253 Show the actual value for glMaterialf().
It might be interesting to see which values are put into glMaterialf(), but I think that's not the real problem.
Could you please provide an actual log?
