Gedit: Alt+F works for me (I am on cosmic using 3.28.1)
LibreOffice: Not sure
Terminal: Teminal ported to gmenu from gtk menu and after that they removed ubuntu-specific stuff.

So it may be related to that because it works in gnome-flashback session, and it compiles with mnemonics enabled.
Rhythmbox: It is also showing shell gmenu. May be unity menubar patch needs to be updated.
Synaptic: It runs as root. So no global menu
