I have the same behavior. After a clean install of 16.04 beta, libreoffice works fine menu in main panel show up. After a few times opening and closing libreoffice the main menu disappears.
After a fresh re-install of 16.04 beta 1, it works again for a few moments before it disappears again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1539939 Title: missing menu in top panel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1539939/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
