--- Comment #17 from Rico kgbricola@web.de 2013-08-13 08:26:57 CDT --- Created attachment 45602 --> http://bugs.winehq.org/attachment.cgi?id=45602 testcase for the opengl information
What do you get when running the attached test case ( wine main.exe )?
Apparently the glxtest ( ./main_linux ) produces something similar to your observations. But this could also mean, that my test is broken.
