Would it be possible to add yet another check for GL_VENDOR == Brian Paul as was done in wined3d_guess_card_vendor a while ago? I realize that it doesn't really fix or improve anyting for you, but at least your code would be consistent. If not, thanks for your time anyway.
Sure, adding an explicit check for GL_VENDOR "Brian Paul" is fine. I initially read the bug report as asking for the removal of the GL_VENDOR "Mesa" check, which I think would be more problematic. I'm still curious what set of GL_VENDOR and GL_RENDERER strings causes an issue here though.
