--- Comment #2 from op (paananen.olli@tuta.io) --- I have similar behaviour with RX 5700 XT and two outputs, one DisplayPort(primary) one HDMI(tv).
If i plugin hdmi cable after i booted the system, everything works fine. Idle power consumption is at ~10-12 watts -> plug in and enable HDMI output, it goes up to ~36 watts, disable or plug out cable -> drops back to ~10-12 watts as expected.
But if i have the HDMI cable connected from the start when i boot up the system, this behaviour appears. Power consumption is at ~36 watts all the time, no matter if i disable HDMI with xrandr or even plug out the HDMI cable.
