Can confirm that for me it was caused by the clock on the top pager updating while using the place compiz plugin, for now have removed the clock (<special>+<alt>+rightclick remove from panel), that's stopped it popping up. I think the problem is with place plugin though and there's a bug report here https://bugs.launchpad.net/compiz-core/+bug/976032.
As for the turns-out-to-be-unrelated windows moving themselves about/jumping to the top of the screen thing that I was having that was caused by wobbly windows plugin which has a snap feature by default set to <shift> changed to <disabled> to stop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/977438 Title: Ubuntu 12.04 gnome classic panel displayed on full screen videos To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/977438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
