(as root): > echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level > or > echo low > /sys/class/drm/card0/device/power_dpm_force_performance_level I did this test and I can confirm that if I set power_dpm_force_performance_level to high or log the flickering stops. So at 144Hz with power_dpm_force_performance_level set to auto there is flickering. With power_dpm_force_performance_level set to high or low this bug is not present.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
