I tried Debian Stable on kernel v4.9 with XFCE and it flickers with rc6 enabled while it stops when I disable it. Unfortunately newer kernels does not respect this parameter anymore. I managed to compile Linux 4.9 on my Arch, but for some reason it cannot load Qt5 libraries, so my Desktop can't start. I was able to run Gnome and I was starring at glxgears (~4500fps) for 15 minutes straight. No flickering... So highly possible this is RC6 related :/</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>
