Public bug reported: If you navigate using the mouse to a menu that has a submenu, for example View -> Toolbars, sometimes the first time you do so, the submenu is empty and only shows as a very small grey rectangle. If you then move the mouse pointer away from the menu, click in the middle of a web page, wait a few seconds, and then try the submenu again, the submenu is appears correctly.
