--- Comment #2 from Nicolai Hähnle nhaehnle@gmail.com --- Thanks for the report. Did the messages
[43513.525167] [drm:si_dpm_set_power_state [radeon]] *ERROR* si_set_sw_state failed [43982.380508] [drm:si_dpm_set_power_state [radeon]] *ERROR* si_restrict_performance_levels_before_switch failed
occur at the same time as the stutter? That would point at a kernel problem.
