Created attachment 103829 [details] libreoffice without appmenu working and kate working. The use of global menu on gtk apps is not working, and is causing missing of menu of application on apps like Libreoffice and Gimp. The attachments shows that appmenu works on kate but not in libreoffice.
LibreOffice does not support global menu protocol. Ubuntu iirc ships custom patches for it to make it work with that. I had a look at it once and all I could find on LO's DBus service is some gnome menu stuff which I couldn't figure out and we don't support.
