Comment 6 for bug 758613

I'm able to reproduce this issue (even if I don't know if the problem is related or not to Unity 2D). Install 'lo-menubar'. Open LibreOffice Writer: nothing appears in the top panel (screenshot attached). Change the focus on another window or show the dash, and then change the focus to LibreOffice: the global menu appears as expected. I have noticed no problems in Firefox. Also I noticed that the problem appears "randomly", that is, the first time I open LibreOffice after logging in I see the problem almost always, but If I do it again, it may or not appear.
