It's hard to believe, but it appears to be a gconf bug, tracked in #848198 :-) There are several reports of this: #853582 #844881 #875954 I could reproduce it on my system by doing 'killall -HUP gconfd-2' and waiting for a couple of minutes. Since this is apparently done on every software update you see these issues popping up. I'm marking it as duplicate. ** This bug has been marked a duplicate of bug 848198 Sporadic gconf error messages -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/872367 Title: Gnome Shell - messed screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/872367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
