Using a whole menu bar just to show *one* menu is ugly from all sides
(that's what happens when we set the XSettings override).

Which applications does this? I know only dconf-editor.

We can not do much about this, we have to options:

1) menus are exported for shell. we don't see menu bar and it is not possible to use menu button in csd window. it will not be shown even button is added to button/decoration layout.

2) menus are not exported for shell. apps will show menubar, csd window can shows this menu under menu button.

There is also Gtk/ShellShowsMenubar, but I don't know what it does...

Oh, indeed, I forgot about it.

But do you know if Gtk+ can insert a menu button into the CSD?

Like this?:

And it is same menu that is shown in gnome-shell panel, right?

I am using:

button-layout = 'appmenu:minimize,maximize,close'

overrides = '{"Gtk/ShellShowsAppMenu":<0>}'

appmenu in button-layout == menu in Gtk/DecorationLayout:
"Gtk/DecorationLayout":<"menu:minimize,maximize,close">

so you could use:

button-layout = ':minimize,maximize,close'

overrides = '{"Gtk/DecorationLayout":<"menu:minimize,maximize,close">, "Gtk/ShellShowsAppMenu":<0>}'

if you want different layouts between ssd and csd windows.

We could use this:
https://git.gnome.org/browse/mutter/tree/src/meta/atomnames.h#n62

to get needed data for appmenu in metacity. but I don't see any need. What point of having button with same content that will be in menubar?

Check mutter in GNOME Shell with "Gtk/ShellShowsAppMenu":<0>. Button with missing-image, that shows same menu that is under dconf Editor menubar. This wont make and difference in how good or ugly application looks.

I guess that requires bigger changes - for example mutter and metacity should somehow (adding that atom to _NET_SUPPORTED?) tell that we support appmenu in decoration and apps should not add useless menu bar. This would require some work in mutter, metacity and gtk+. Since they have not done that for mutter I am not interested in writing patches that most likely will not be accepted. I have tried twice - org.gnome.Shell bug, per session overrides bug. Seems that they are not interested in anything that is unrelated to GNOME. :(

I think I have seen that in past, but don't remember if it was my system
or just a screenshot.
