Extra information about my system to help debugging:

Current behaviour

• I "installed" the Joplin AppImage linked here
  
• I allows AppImageLauncher to "integrate" the app and set up the icon for it.
• In my dock, I see an error icon
  
• If I navigate to the AppImage in /home/me/Applications the AppImage doesn't have an icon
  
• If I alt+enter to see properties I do see an icon correctly, so it's definitely in there somewhere
  

Expected behaviour

I expect the icons to appear everywhere and not just in the AppImage's properties.

Logs

I don't think there are any logs relating to this, though I'll follow any instructions to grab anything.

Update: I reinstalled using the suggested script and I still have the same broken icon on my dock. 🤔

problem is that its app_id has '/' character in its name, appid is whats used to pick icon for a window, and it is causing issues

I did some more debugging and noticed that my desktop (also running Fedora 40) doesn't have this issue, so I kept digging in. I have the icon at ~/.local/share/icons/hicolor/512x512/apps/joplin.png and in my desktop icon file I have

[Desktop Entry]
Encoding=UTF-8
Name=Joplin
Comment=Joplin for Desktop
Exec=env APPIMAGELAUNCHER_DISABLE=TRUE "/home/zachery/.joplin/Joplin.AppImage"  %u
Icon=joplin
StartupWMClass=Joplin
Type=Application
Categories=Office;
MimeType=x-scheme-handler/joplin;
X-GNOME-SingleWindow=true // should be removed eventually as it was upstream to be an XDG specification
SingleMainWindow=true

So the icon and the image appear to exist in the right places, but I'm not sure why they aren't connecting yet.

problem is that its app_id has '/' character in its name, appid is whats used to pick icon for a window, and it is causing issues

I would expect this is probably why the appimage itself doesn't have the right icon, but the "installer script" that I fell back to when the appimage didn't behave as expected seems to my untrained eye to account for this by setting up its own .desktop file that manually specifies.

gnome uses startup-wm class to find icon i think, hence its correct in fedora, but other wms, specially wlroots, they use app_id only, hence the issue in them

[zach-delong]

hence its correct in fedora

Both of my computers are Fedora, but one of them (my laptop) is showing the broken icon, which is strange. I was just using my laptop as normal and installed something (wine) and the icon magically fixed itself. I am not sure why the icon would just fix itself during install but not during reboot, but apparently something got shaken loose...

I have tried to reproduce this again and haven't been able to. I think the issue is either resolved by a recent patch or it's harder to reproduce than I realized. Either way, good to go for now.
