i am having same problem, after dist-upgrade yesterday (i am also debian unstable). i can dismiss the menu by reclicking it, but nothing in the menu responds.
additionally, when mouse goes to upper left corner, or one clicks on the Activities menu, gnome-panel becomes completely unresponsive and need to do service gdm3 restart. i see this in ~/.xsession-errors each time i click in gnome-panel: JS LOG: pushModal: invocation of begin_modal failed Window manager warning: Log level 8: meta_end_modal_for_plugin: assertion `compositor->modal_plugin == plugin' failed JS ERROR: !!!
