CPU load seems not to be affected. I can't reproduce screen corruption when using xf86-video-intel with --enable-debug=full. I can't tell anything regarding the slownes because the debug version runs generally much slower. I've attached a new log file with debugging on.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
