The right fix is to be able to pass the buffer from the game to the compositor and only return it once the compositor has finished with it, alas that dream remains a long way off. What's the game setup you are using, or does it simply always happen once windowed? And of course there may be other reasons behind the flicker hence downloading a copy myself to investigate.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
