Summary: AppImages Make System Tray Application Launcher Icons Invisible

Description nekonexus 2021-02-24 20:13:20 UTC
I use AppImage launcher to integrate AppImages with my desktop and, when I approached the developer about it, I was told that it was an icon issue with KDE.


1. Have AppImage Launcher installed
2. Attempt to run the AppImage to have it integrated
3. Application launcher and system tray icons lose their icons for the rest of the session

The system tray icons can be restored by exiting the relevant applications entirely and relaunching them, but this does not fix the missing icons affected for apps in the application launcher.

App icons shouldn't disappear during user operation

I've managed to reproduce this on every distro I've ever used with KDE, personally

I think similar situation is when user changes the icon theme - Neko, can you change icon theme is System Settings? Is issue exactly the same?
Comment 2 nekonexus 2021-02-28 21:11:07 UTC
The exact same situation occurs with the system tray, in this scenario, yeah.

However, there's one difference:
in the application launcher, instead of some icons turning into white sheets of paper, they also go completely invisible like the system tray icons that do

[dataengines/sni] Reapply IconThemePath on icon theme change

SNI can have custom icon path in IconThemePath attribute.
StatusNotifierItemSource uses custom KIconLoader to add this theme dir.

KIconLoader forgets this path on any system change
(for example when icon theme is change in system settings).

Reapply custom theme path on KIconLoader::iconChanged.
FIXED-IN: 5.22.0
