--- Comment #8 from Konrad Materka <mate...@gmail.com> --- Try this: rerun Plasma with debugging: QT_LOGGING_RULES="kde.systemtray=true" plasmashell --replace & check if you see your applet in logs (console output), for example: kde.systemtray: Adding applet: "org.kde.plasma.battery" Do you see any errors/warnings? While looking at console output, open system tray configuration. Go to Entries. Do you see anything suspicious? check ~/.config/plasma-org.kde.plasma.desktop-appletsrc file, sections: extraItems= hiddenItems= knownItems= You can have it multiple times, for example some old configs or configs from several panels (if you use multi-screen). Check all of them, do you see anything suspicious? -- You are receiving this mail because: You are watching all bug changes.
