I’m running KDE Plasma on Arch Linux. Since updating to Plasma 6.7, every time I launch a Flatpak-installed application an icon for that app appears in the system tray. I believe this is caused by the new “Background apps” feature.
The problem is that the icon shows up even for applications that don’t actually run in the background — for example Postman or LibreOffice. As soon as I close the app, the icon disappears.
Is this the expected behavior? I find it pretty annoying, and I’d like to know whether there’s a way to disable it, or to limit it to apps that genuinely keep running in the background.
Seeing this exact behaviour on Arch + Plasma 6.7 as well.
Seems to be that all flatpak apps get a tray icon no matter what now, doesn’t seem to affect anything non-flatpak. Other odd behaviour includes the icons being persistent after a flatpak is closed. Sometimes the icon goes away after 5 seconds, sometimes it goes away after 20 minutes.
Very annoying and would like to see the tray behave like it used to.
The problem only occurs with Flatpak apps — native packages don’t trigger it.
I also tested this across three of my own Arch Linux installations. On two of them the issue appears, but on the third it doesn’t. The only difference I can find between them is the display server: the two machines where the problem occurs are running X11, while the one that works fine is on Wayland. Could that be the cause?
