Several MATE themes do not render vala-panel-appmenu applet correctly

[flexiondotorg]

Expected behaviour

When the vala-panel-appmenu Global Menu applet for MATE is added to a panel, the background of the Global Menu applet should use the same background colour as the panel.

Actual behaviour

When the Global Menu applet is used with the following themes the Global Menu applet background doesn't match the panel background.

• BlackMATE
• Blue-Submarine
• GreenLaguna
• Green-Submarine
• TraditionalGreen
• TraditionalBlue

Here is an example screenshot of the issue.

Steps to reproduce the behaviour

• Run the Ubuntu MATE 18.04 daily image live session in a VM
• Right click a panel, select "Add to panel..", select "Global Application Menu" and add it.
• Open MATE Terminal.
• Open Appearence control center applet.
• Select one of the affected theme listed above, focus the MATE Terminal window and look at the Global Menu.

• 1.20

I would like to fix that but global menu applet doesn't work correctly in my 18.04 installation.
Read my comment in ubuntu-mate/ubuntu-mate-artwork#3 (comment) and followers.

Try sudo apt install appmenu-gtk2-module appmenu-gtk3-module, reboot and then add the Global Menu to a panel.

[raveit65]

Already installed.

@raveit65 Can you try using MATE Tweak to switch layout to Cupertino. That includes the global menu.

[raveit65]

But the globalmenu is there, only the menu isn't moved from apps to the panel.
I think i tried Cupertino layout already, but i can try it again.

[raveit65]

Same disappointing result with Cupertino layout.
I see the menus only in panel if the desktop has focus.
Menus from other application won't display in panel with globalmenu.
Note , the installation have latest updates from today.

[raveit65]

Hmm,
~/.config/dconf/user was owned by root ---> fixed
What is right setting for globalmenu gsettings keys?

rave@ubuntu:~$ gsettings get org.mate.interface gtk-shell-shows-app-menu
true
rave@ubuntu:~$ gsettings get org.mate.interface gtk-shell-shows-menubar
true

[raveit65]

I notice that other folders and files were owned by root in my user accout.
I never saw that with fedora...
Ok, after deleting and re-creating user account the menus are in panel \o/

@flexiondotorg @rilian-la-te
It is quite usual the themes use another background color for GtkFrame in general.
Is there a reason why vala-panel-appmenu use a a scrolledwindow and a viewport there?
This sounds really weird for me, see

@sc0w
For TOK themes i'd like to remove the gradient background for the panel at https://github.com/mate-desktop/mate-themes/blob/master/desktop-themes/TraditionalOk/gtk-3.0/mate-applications.css#L103
and for

/* main menu */
/* set normal menubar button */
.mate-panel-menu-bar menubar {
    padding: 0px;
    background-image: none;
}

Because the background-image isn't use everywhere for the panel.

1. It uses scrolling, because if monitor have small resolution, then big menu will move contents of panel out of monitor. With scolling, it will just scrolls.

@raveit65 In case you missed it, @sc0w gave you a thumbs up to modify TOK 😄

Ok, that makes sense.

[raveit65]

done.
