Wayland Icon Instead of the Mercury Icon

[tylercritchlow]

I'm running Wayland on Tuxedo OS, which uses deb packages, and the icon changes from the Mercury icon when it is not launched to the Wayland icon when it is. I tried vanilla Firefox and it doesn't do this.

What I found: https://community.kde.org/Guidelines_and_HOWTOs/Wayland_Porting_Notes#Application_Icon

Application Icon On Wayland setWindowIcon() no longer works. This also means that currently is not possible to set a per-window icon >(because the xdg-shell standard doesn't allow it). It is still possible to set the main application icon that will be shown in >task managers and window decorations:

The name of the application icon will be fetched from the .desktop file of the application. The name of the .desktop file must adhere to the reverse domain standard (e.g. org.kde.app.desktop).

Most of the KDE applications are already working fine because KAboutData takes care of all the necessary steps. If for >some reason your application is not using KAboutData, you need to manually call >QGuiApplication::setDesktopFileName().

@tylercritchlow I can't find any examples of this being used in a firefox .desktop file

I've found a workaround for this issue: as mentioned in workaround no.1 in this Bugzilla issue for Firefox Beta/Wayland showing the Wayland icon , adding --name Mercury to the Exec lines in the desktop file will properly group the windows:

- Exec=mercury-browser %u
+ Exec=mercury-browser --name Mercury %u

( repeat for subsequent [Desktop Action*] sections aswell)

turning this:

nevermind that attempted commit/PR, a much nicer-looking fix was actually featured in #84 , where the StartupWMClass is just set to mercury-default instead of the stock mercury
