However, in gnome-shell, touching the top-left 'Activities' menu results in a quick flash of the menu button, but not the launching of the overview. Once in the overview (via mouse/keyboard/swipe-from- left), touching on an application icon (in either the left tray or the applications grid) results in the application icon flashing, but not activating. A long-touch will bring up a menu in which touching on "new window" works properly. Additionally, touching the "show applications" grid button works, as do other components of the top bar, its only the the "activities" menu button and app icon launchers that are "registering" a touch but not activating properly.
