On Linux, when PyGObject is available, pystray uses its appindicator or gtk backend. With these backends, run_detached() does not display anything by itself: it only schedules the icon creation on the GLib main loop, and expects the application to run that loop. The main loop was never started, so the icon was never displayed and its menu never worked, while the log still reported "Tray icon has been displayed". Without PyGObject, pystray falls back to its xorg backend, which runs its own loop but relies on XEmbed: on Wayland sessions (e.g. KDE Plasma) the icon is shown as a blank square that barely responds to clicks. Start the GLib main loop in a daemon thread when a GTK-based backend is used. Other backends (xorg, win32, darwin) are unchanged. Tested on Fedora 44 with KDE Plasma (Wayland), Python 3.14, pystray 0.19.5.
