SUMMARY Elisa continuously signals that the Position property has changed while playing which causes excess DBus traffic and the MPRIS spec [1] explicitly says should not be done. [1] https://specifications.freedesktop.org/mpris-spec/2.2/Player_Interface.html#Property:Position STEPS TO REPRODUCE 1. Play a song in Elisa 2. Run dbus-monitor OBSERVED RESULT It continuously emits PropertyChanged for Position EXPECTED RESULT It doesn't spam the bus SOFTWARE/OS VERSIONS KDE Plasma Version: 5.17.80 KDE Frameworks Version: 5.66.0 Qt Version: 5.13.2 ADDITIONAL INFORMATION The UnityLauncher DBus could probably also be throttled more, signalling a change of 0,001446 for an item that is 300px wide in task bar is less than a one pixel change.
