Hi.

PC:
Asus UX305F
KDE Neon 5.9
Application Menu Widget enabled in Settings

Problem:
I can get only KDE application menus working, it doesn't work as expected with non-KDE/Qt apps:

1. Firefox - I get the app menu into Application Menu Widget, but the menu isn't functioning - cannot open sub-menus.
2. GIMP - no GIMP menu in the Application Menu Widget at all.

Any solution to the problem ?

Regards
Artūras
