No/slow appearing global menu in Unity

[Marius B. Kotsbak]

Moving the mouse to the top of the screen, no menu appears. It seems after some time it is available.

Similar happens with libreoffice 3.6.2 rc2.
After quickly opening/closing/opening any Libreoffice application /writer/calc/impress ... the menuebar is visible (in 3.6.1 it was not, so situation gets better ;-) but it doens't work, also keyboard shortcut's don't ...

After closing an libreoffice application and waiting some time (approx. 10-20 secs.) menuebar is working again.

Status changed to 'Confirmed' because the bug affects multiple users.

If I open an XLS email attachment, no Calc menu. If I open Calc first and then the attachment, I get a menu. The same is true of a TXT file if I choose "Open with Calc" without first opening Calc or opening the file from within Calc.
