I have installed lib32-libappindicator-gtk3 and libappindicator-gtk3 but it stil wont show in the system tray , works fine in X11

Have you tried any other appindicator app under KDE?
I know that it works to some degree, but it isn't as nice as on Gnome.
For me radiotray-ng works fine under Wayland/Gnome.

Same here, no tray icon in gnome3, works fine under plasma6/wayland..

[xensurve]

here's a work around, force it to use X11 Backend

GDK_BACKEND=x11 radiotray-ng

[ebruck]

Same here, no tray icon in gnome3, works fine under plasma6/wayland..

@idovitz do you have this extension installed for gnome3?
https://extensions.gnome.org/extension/615/appindicator-support/

[idovitz]

Yep, installed it. Only show tray icon with xensurves workarround.

[ebruck]

@idovitz if you run this command what does it print?

GDK_BACKEND=help radiotray-ng

[idovitz]

Supported GDK backends: wayland x11 broadway

the .desktop file needs to be altered.

$ cat /usr/share/applications/radiotray-ng.desktop
[Desktop Entry]
Categories=AudioVideo;Audio;Player;GTK;
Comment=Internet Radio Player for Linux
Exec=/usr/bin/env GDK_BACKEND=x11 /usr/bin/radiotray-ng
Hidden=false
Icon=/usr/share/icons/hicolor/256x256/apps/radiotray-ng-notification.png

If you have a startup application, that needs to be changed as well
Command:

/usr/bin/env GDK_BACKEND=x11 /usr/bin/radiotray-ng

still an issue with radiotray-ng 0.2.8,
libappindicator-gtk3-12.10.1, plasma 6.1, wayland, breeze-dark theme

setting GDK_BACKEND=x11 does not help

same issue with radiotray-ng c7f5bd0

same issue with libayatana-appindicator

the radiotray-ng.png icon is loaded

$ strace -ff -s 999999 ./result/bin/radiotray-ng 2>&1 | grep -F .png
[pid 295794] openat(AT_FDCWD, "/nix/store/1h6nmjg8cdyk8n74xnybypcsy3xsdd7q-radiotray-ng-0.2.8/share/radiotray-ng/radiotray-ng.png", O_RDONLY <unfinished ...>

the radiotray-ng.png icon is visible in the about dialog

maybe an upstream issue with libappindicator
