Generic icon for application on Wayland KDE.

[Barafu]

When I run my application in AppImage on KDE Wayland session, it has a generic Wayland icon in top corner and in Alt-Tab, but with a proper icon on the menu or in taskbar.

My app exports Wayland app ID, which is the same as icon name and desktop file name. It works properly outside of AppImage.

What else should I do?

Manually copying an app .desktop and icons to the host system fixes this, now the AppImage runs with the proper icon.

I have located the workaround: After the AppImage was created and then installed using GearLevel, the name of the .desktop entry that GearLevel creates matches the name of the command (binary file), not the original name of the .desktop that I provided in AppDir.

So, if I set the AppID in the source of the app to match its binary file name, then the icons show properly, but only after the installation with GearLevel.

However, doing so is against FreeDesktop's recommendations, which say that the name of the .desktop file must be qualified with the developer's name.

I build AppImage with this command: ARCH=x86_64 ../../appimagetool-x86_64.AppImage AppDir

OK, I can detail the issue now.

When I create appimage, the appimagetool reads field Name from AppDir/myapp.desktop and uses it both for the application name and for the file name of application.desktop file that will be put in menu be GearLevel. However, the name of the .desktop file must be qualified with the developers' domain (developer-myapp.desktop) according to specification. The desktop-file-validate tool will even complain if the name of the files does not contain a hyphen.

The name of the file should be left alone, as is in AppDir folder.
