I'm also effected by this bug - there are 2 workarounds I'm using: 1) CTRL + W wil show all open windows.
2) ALT + F2 then typing unity --replace will restart Unity and always fixes the problem. There are many different problematic scenarios, which only effect LibreOffice. They mainly occur when opening an .ODG/.ODP etc. file, however sometimes occur when opening an LO application. I don't remember this happening on a clean install, so possible caused by an update... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1027000 Title: Intermittent launcher icon/Alt+Tab entry for LibreOffice To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1027000/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
