Requesting a GL < 3.0 > context with forward compatible is a dangerous game to be playing. Just checked with the glx code and I think you got the point here.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
