Bug Description
After upgrading from 20.04 to 20.10 system is unusable anymore due to GPU issues with nouveau. Same system worked fine on 20.04.
Switching to nvidia proprietary driver and Xorg fixes the issue.
Symptoms:
System starts just fine, but overall UI performance is bad, everything seems slow and CPU usage seems too high even when idle. After a while UI freezes completly. Sometimes it recovers after several minutes, other times it doesn't and system freezes forever, requiring hard reboot.
Setup: Ubuntu 20.10. nouveau. Wayland. nVidia GTX 1080 Ti. Intel Xeon E3-1231 v3.
dmesg output attached.

Tried 5.9.1 mainline kernel and got the same issue. The only difference is Wayland recovered much faster (under 1 min). I didn't wait after recovery to see if system will lockup completely and rebooted with proprietary driver. Attaching dmesg output.
