Tauri's default tray uses libayatana-appindicator, which by design does
not dispatch primary-click events to its client — libayatana delegates
every left-click to the libdbusmenu-managed menu. The existing
show_menu_on_left_click(false) setting and TrayIconEvent::Click handler
never fire on Linux. Confirmed present in tray-icon 0.21.x and 0.22.0
(the newest release).
Switch the Linux backend to ksni, a pure-Rust StatusNotifierItem
implementation that exposes the full SNI protocol including Activate
(left-click), SecondaryActivate (middle), and ContextMenu. Same SNI
compatibility as the previous backend — works wherever the panel
already handled our tray (KDE, GNOME+AppIndicator, XFCE/Cinnamon/MATE,
wlroots trays). Flatpak just needs the --talk-name=org.kde.
StatusNotifierWatcher permission which is already in our manifest.
Tauri's tray stays on macOS (no Windows client is shipped). The
dispatch lives in tray.rs behind cfg(target_os); Linux delegates to
the new tray_linux_ksni module. Playback-control menu events
(tray:play_pause, tray:next, tray:previous) still emit into the main
webview window, so frontend handlers keep working unchanged.
