Created attachment 661268 [details] picture of Bad mode Description of problem: Occasionally gnome-shell goes into a weird mode. And I don't know what the trigger is. In this mode, the application windows appear to move up [north] to make space for message tray at the bottom - almost like the 'overview mode'. Also the title bar of the applications appear to disappear in this mode. I can restore to the regular screen by clicking the mouse anywhere. Version-Release number of selected component (if applicable): kernel-3.6.9-4.fc18.x86_64 gnome-shell-3.6.2-3.fc18.x86_64 How reproducible: Happens a few times every day. Steps to Reproduce: I'm unable to reproduce on demand [but happens when I least expect it] Actual results: Expected results: Additional info: The machine is a thinkpad t420s [intel sandy bridge cpu/gpu/wifi]. It was runing F16 x86_64 until I upgraded to F18 on Nov 19th [during TC7 beta timeframe?] via preupgrade to F17 - and then with fedup to F18. And the problem was noticeable prettymuch since the upgrade to F18. Attaching a photo of this mode [as I can't take a screenshot in this mode]. Also attaching a screenshot of the regular mode aswell.

ok - perhaps this is a gnome-shell feature :( I now see I can force this mode by pushing the mouse down [south of the screen] - and holding it for a couple of sec. Can I disable this mode?
(In reply to comment #2) > Can I disable this mode? https://extensions.gnome.org/extension/151/hide_notification_bar/ can do that I think.
