After switching desktops, the panel won't update the current desktop items
Using a fresh system install without messed up config.
This same problem occurred when I was using lxqt, for some reason this don't occurs on xfce, so I don't think this is related to openbox.
Does someone have a solution for this?

Distro: Arch Linux
Kernel: 4.4
Openbox: 3.6.1
plasma-desktop: 5.8.5-1
