--- Comment #5 from Rico kgbricola@web.de 2008-08-20 11:53:33 --- Are we talking about this patch http://bugs.winehq.org/attachment.cgi?id=15361 ? If so, please have a look at the docs (e.g. http://www.opengl.org/documentation/specs/man_pages/hardcopy/GL/html/gl/scis... ). Passing invalid values to a function isn't the right way to go, is it? What do you expect as a result? I don't think it is the right behaviour because you could only expect garbage.
