I am experiencing similar issues with 12.04 Unity. Though I am not sure when/how it occurs, certainly not the 'click top left icon' jig But I have noticed most of the times after lock/unlock, the windows borders are gone.
I tried 'unity --reset' once but that didn't seem to resolve this. Please let me know what all information to collect for debugging this and I'll get it done. It is really painful to logout-then-login to resolve this each time it occurs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/771929 Title: Window Decoration disappears after clicking on the top left icon To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/771929/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
