[stop (whoopwhoop)]

Also switching to tty and back (Ctrl+Alt+F2; Ctrl+Alt+F7 f.i.) sometimes works, sometimes results in a black screen with a cursor and sometimes results in a corrupt desktop (see screenshot) with sets compiz jumping to 100% cpu usage. The black screen and corrupt desktop are both completely non operational (cursor does move).

Another thing is when I select "Log Out..." the desktop always crashes, I get a non interactive tty which still shows information about booting the system. I do not get the login screen.

I was told it is not the same as #836616

Status changed to 'Confirmed' because the bug affects multiple users.

I had similiar situation. But I had also installed google-desktop-linux package. After uninstall it there is not problem with consumption 100% of cpu.
