Two issues Tray icon resizing (doesn't work) and xdg autostart throws dbus warnings
OK the panel plugin properties where is says resize icon simply does not work. Recently my distro switched from launching with dbus to launching with xdg autostart. From a reboot or starting the computer it launches and works with no errors. However if you log out of your session and log back in then notifyd throws warnings about the missing dbus service. The warnings say something about the dbus service name is not known so notifyd cannot read the unread messages.
