Public bug reported: This seems to occur after gnome-shell says system needs a reboot. So I'm not sure whether this is actually a nvidia problem at all. It also has happened when coming back after a lock screen or after a suspension. But none are repeatable as it is not every time hence my suspicion of gnome-shell.
