Shortly before the bug occured, the window suddenly stops rendering (it logs no FPS). After restarting glxgears the window is still black and the FPS runs as if it were not synced (several hundred FPS). This bug also has just happened again shortly after Xorg is restarted; by chance I caught it stop, and it only goes black once the window becomes obscured.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
