When "Wacom tablet settings" is set to autoload, it is always visible, regardless of having a tablet connected.
the auto load depends from a dbus service being present or not, which is probably not dependent to the tablet being phisically connected or not.. the applet should autohide when there isn't a tablet connected, that's a bug of the applet itself
It actually depends on both availability of the service and having at least one tablet connected https://cgit.kde.org/wacomtablet.git/tree/src/applet/package/contents/ui/main.qml?h=3.1#n42 So far I can't reproduce the issue, widget auto-hides and shows up automatically for me just fine :/ Could you please share which version of wacomtablet you're using, and make sure that: 1) element visibility is set to automatic in system tray settings 2) wacomtablet widget reports that no tablets are connected when it's still visible
