It seems there is a problem with powersafe:

With auto:
echo auto > /sys/class/drm/card0/device/power_dpm_force_performance_level

you will see heavy screen flickering on higher display resolutions (2560 x
1440). It's ok with 1920x1200.

With low or high:
echo low > /sys/class/drm/card0/device/power_dpm_force_performance_level or
echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level

there is no screen flickering with all display resolutions.
