Public bug reported: When I switch users via the whisker menu (dm-tool switch-to-greeter) and login as the second user, I see permanent heavy cpu usage of xorg.
I have tried the nouveau drivers as well without success. I am currently using the latest nvidia from ppa, but with the official nvidia drivers from bionic, I had the problem as well. Logging out and logging in as another user does of course work. Meaning: I cannot switch users anymore...
