Seems to be initiated when jumping between full screen apps, particularly to/from nautilus. When it happens, Libreoffice also disappears from the alt-tab list and, if minimised, also from the expo (ctrl-w) view. So it completely disappears from view and access from Unity when minimised. However, if you close all other apps then start a new app then Libreoffice springs back into view.
I originally had this problem with Libreoffice 1:3.4.5 from the ppa so I purged it back to the standard 1:3.4.4 packages but find the problem still exists. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/928438 Title: LibreOffice doesn't have window title or buttons in Unity To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/928438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
