Attachments:	Global Menu still showing Elisa menu after it's minimized while Window Title area becomes blank Window Title displaying Elisa only when its window is active MacOS Ventura with the same orphan menu problem

Description Sadi 2023-08-24 08:32:33 UTC

This has been around for some time actually, and there are two different problems probably related to the same issue.

1) I have a startup script that launches Elisa and then immediately minimizes its window upon login. But the Global Menu applet still displays its menu. However, Window Title applet doesn't do that, e.g. after Elisa is minimized, its title goes off.

2) Sometimes Global Menu displays the previous active app menu when it can't show any menu from the current, which happens with some (not all) GTK apps, like Synaptic Package Manager. For instance, when I launch Synaptic while there's an active Dolphin window, Global Menu still displays its menu when the active window is Synaptic. However, Window Title applet doesn't do that, e.g. it replaces Dolphin with Synaptic Package Manager, while the menu following this title is from Dolphin window behind the active Synaptic app window.

When it's in this state, is another app active? Or is Plasma itself active?

Case 1: AFAIK it happens only during login when Elisa starts from an autostart script that merely launches the app, waits 2 seconds, and then executes:
xdotool windowminimize `xdotool getactivewindow`
At this time there's no active app window, although there are some other apps minimized or closed to system tray (unfortunately Elisa doesn't have these features ; -)
Naturally, it doesn't happen when Elisa minimized resulting in another open app window automatically takes over the active state.

Case 2: It happens when there is another app window open. Apparently, Global Menu applet either doesn't realize that Synaptic is the new active app window, or wrongly decides to keep the previous active app menu because it can't get  any menu information from Synaptic.

How strange. Thanks.

I've just noticed that MacOS 13 (Ventura) oddly has the same problem, too - if this means anything. ;-)

applets/appmenu: Fix displaying menu of the previous active window

We need to break the DBusMenuImporter::menuUpdated() signal connection
when the active window changes. Otherwise, it's possible that the
menuUpdated signal will be emitted and the menu will be marked as
available.
