Do you still get the glitches if you connect a secondary display or > disable dynamic clocking? To disable able dynamic clocking (as root): > echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level > to re-enable it (as root): > echo auto > /sys/class/drm/card0/device/power_dpm_force_performance_level The High value makes the glitches go away. As soon as I set the Auto value, the glitches reappear. I don't have access to a second display to test right now, only tomorrow. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
