With x11-misc/appmenu-gtk-module[-gtk2 -wayland] installed, libreoffice main/top menubar is gone. Workaround to get the libreoffice main/top menubar back: - unset GTK_MODULES; libreoffice ... - or simply remove x11-misc/appmenu-gtk-module (and relogin) Basically, what x11-misc/appmenu-gtk-module does is - install a bunch of files - add appmenu-gtk-module to the GTK_MODULES environment var: GTK_MODULES=canberra-gtk-module:appmenu-gtk-module:canberra-gtk-module:appmenu-gtk-module Note the duplicates in GTK_MODULES. Anyway (as expected), removing the dupes doesn't make any difference. Reason for installing x11-misc/appmenu-gtk-module was an attempts to get the main/top menubar back into gtk3 apps, especially dev-util/meld-3.22+ (which now uses gtk3). So far, with x11-misc/appmenu-gtk-module installed, I only experience negative effects: - meld (and other gtk apps) say: Gtk-Message: ... Failed to load module ""appmenu-gtk-module"" - libreoffice loses the main/top menubar Note the double "", unsure how this may be related ... In the current state, I really doubt what purpose this package serves. Really, is there currently any known positive impact or did I hit a bug?
