Thank you. So I tried "echo high >
/sys/class/drm/card0/device/power_dpm_force_performance_level" without "" as
root and without restarting I set the refresh rate to 144hz and there is no
more artifacting/flickering. Setting it back to auto causes there to be
artifacts/flickering. So its something that has to do with DPM? I havem my
dmesg attached when setting it to high.
