Incorrect app icon in the GNOME dock

(#160) Bug Confirmed desktop packaging

Summary

I've pinned Fluxer (installed from an AppImage) to the GNOME dock, but when I run it, a second icon for "fluxer_app" appears with a generic program icon, instead of just the active application marker under the first one. image

Steps to reproduce

Pin Fluxer to the GNOME dock
Open the app

Environment (optional)

stable (d90628a), 2026-02-16 10:10:38 UTC, Electron 39.2.7, Linux 6.18.9-1-default (x64), desktop stable 0.0.8 GNOME 49 on openSUSE Tumbleweed

Reopened because another user found the wrong StartupWMClass and it was bulk closed without a fix.

It looks like the .desktop file at /usr/share/applications/fluxer.desktop specifies the wrong StartupWMClass. Manually editing it to apply this diff fixes the issue:

- StartupWMClass=Fluxer
+ StartupWMClass=fluxer_app

~~Probably whatever electron configuration is used to generate the .desktop file needs to be updated~~ Actually, I think this is a packaging issue, not a Fluxer issue. If you're on Arch Linux and using the package from the AUR, the desktop file is provided by the package: https://aur.archlinux.org/cgit/aur.git/tree/fluxer.desktop?h=fluxer-git

Thank you for the tip, I used the Pins app to fix that, but I hope this won't be necessary in future releases.
