Description Lemuel Simon 2022-06-25 17:26:08 UTC 
SUMMARY
Referring to the bug reports here: https://github.com/Zren/material-decoration/issues/63 and here: https://bugs.kde.org/show_bug.cgi?id=455152


STEPS TO REPRODUCE
1. Launch Strawberry(Qt5) or Claws Mail (GTK3) with their tray icons enabled.
2. Toggle-show Strawberry's/Claw's main window with tray icon.
3. Close main window by clicking 'X' (the tray icon should still be there).
4. Press Strawberry/Claws tray icon to show the main window again.

OBSERVED RESULT
The appmenu is no longer exported; KDE's Global Menu, Psifodotos' Appmenu and Zren's Material LIM no longer display the menu. Running `xprop` on Strawberry confirms that the menu is no longer exported.

EXPECTED RESULT
The Global Menu is exported.

ADDITIONAL INFORMATION
For testing, I've launched an XFCE session with Valapanel's Appmenu (https://gitlab.com/vala-panel-project/vala-panel-appmenu) and tried to replicate the bug, but it doesn't occur there at all.  Strawberry's and Claw's menus are always displayed when the main window is visible, even when going through the aforementioned steps. So, I believe it is an issue with how the appmenu is exported in KDE's service daemon. 

Here is some output from `xprop -f _NET_WM_ICON 8i | sort`:

Forgot to add the rest of the Summary...
The appmenu of Claws Mail (GTK 3) and Strawberry(Qt5/6) will stop being exported if they are toggled by tray icons. If the main window for Strawberry was exited, the main window will respawn from the tray without the menu being exported. With Claws Mail, the bug is triggered by simply toggling the main window with the tray icon. In both instances, one must relaunch the applications to see the menus exported again.
