I had this problem for years, even on LMDE / Debian installs. I had forgotten about this bug report but now realize that since I switched from Gnome to xfce the problem has gone away. I now use xubuntu and add compiz/emerald to it. This makes sense since as I said back in 2011 I'm fairly certain this is an issue related to timing and menu caching which would be specific to gnome.

As far as I can tell, this happens randomly for all drop and sub menus, including menus for applets/indicators in the gnome-panel, gnome-terminal, thunderbird, gedit, nautilus, and all other applications I've tested. It seems to happen randomly, some menus display fine, but some don't display. Interestingly, when the menu doesn't appear, and you move your pointer to the place where the menu should appear, the menu suddenly appears. Also, this seems to happen once per menu, so if a specific menu didn't display, the second time you click that menu item, the menu does display, and will display properly the next times you click it. But, if you restart that application, it will start over again. The problem doesn't happen after disabling compiz. When compiz is started again, the problem is back. Maybe this issue came to Maverick with the new X.Org Server 1.9 release.
