[BUG REPORT] Unreasonably high power consumption in RDP session on Ubuntu with RTX 3090

I’m connecting to Ubuntu with latest nvidia drivers and checking power draw with nvidia-smi:

I get 108-110W without running any tasks. Same problem was on default ubuntu drivers (550).

When I logout from RDP session and check nvidia-smi with anydesk/from display/from ssh, power draw returns to normal:

Maybe 110W draw is expected because of video encoding for RDP? It seems like too much though.
