To fix flickering, set mclk to high (echo > 1 > /sys/class/drm/card0/device/power_dpm_force_performance_level) Hello iuno, is there a easy way to achieve setting clock.default_dispclk to 625 Mhz? like setting dpm performance level to high? I'm using radeon open source driver with Asus R9 390X / MG279Q on Ubuntu 17.04. 120hz is working fine with dpm performace level high. 144hz has blurry image and one faulty line on the left side Thank you.
