I confirm: happened to me when I was using cinnamon
I don't see this problem anymore, tested with both Firefox and Chromium web apps. Anyone can confirm ?
Still having this issue with Firefox via Flatpak
The problem still happens. If you already have a browser window opened, it works correctly, otherwise, all apps launched by Web Apps get the same icon of the first app launched.
Linux Mint 20.1
Cinnamon 4.8.6
Brave Version 1.25.68 Chromium: 91.0.4472.77 (Official Build) (64-bit)EDIT: Looks like it's a Cinnamon bug. I've tested in Mate Desktop and it works fine with Mate.
This issue happens to me too. The icons of two Goland windows are shown as the Chromium icon.
I don't know how and when does it happen.
Linux Mint 21.1 Cinnamon
Cinnamon 5.6.5For me it was the mismatching
StartupWMClassin.desktopfile and the result ofxprop WM_CLASS.
I wrote my fix here: https://unix.stackexchange.com/a/805588/343279Sounds like the
Web Apptool needs to set theStartupWMClassto what Chromium makes!Chromium ignores the --class flag when --app=URL is used and instead derives WM_CLASS from the app URL itself. It takes the URL host+path and converts it to a valid X11 class by replacing characters like . and / with _. So https://www.google.com/maps becomes www.google.com__maps.
For Firefox-based browsers, the exec string passes --class WebApp-{codename} and Firefox respects it, so WM_CLASS stays as WebApp-{codename} — the manager-assigned value.
When I start the first app, the correct icon is shown on the panel. After that, any app launched is assigned the same icon of the first launched app.
Tested on Linux Mint 20.1 Cinnamon
