Description Christian Persch 2017-11-05 09:35:46 UTC 
When a GtkMenu is attached to a window (gtk_menu_attach_to_widget), then shown with gtk_menu_popup(), and then after it's shown the window closes (but the app continues to run, for example because it has other windows open), the popup menu becomes a grey square on top of the other windows, and there are loads of 

Gtk-CRITICAL **: _gtk_widget_captured_event: assertion 'WIDGET_REALIZED_FOR_EVENT (widget, event)' failed

warnings on console.

You can repro this in gnome-terminal as of commit fd1d562f57f1d0033130a39a5ed49e6d3d6fe133, by opening a 2nd window, typing "sleep 5; exit" into the shell+return, then while it's sleeping right-click to open the context menu. I'm going to workaround this in g-t now, but

IMHO, when the widget a menu is attached to is destroyed, the attached menu should automatically be gtk_menu_shell_deactivate()d by gtk+ if it's on-screen at that time.
