High CPU usage with calculator enabled

Description

I'm running a FreeBSD guest inside a Windows host using Virtual Box. There are 4 CPUs and 8GB of RAM used by the guest (the host has 16GB).

Using the XFCE4 as the desktop, I have the following plugins enabled:

. screenshot . clipboard . weather . clock

If I add the calculator plugin, top starts showing 20% CPU-utilization by the new wrapper-process, and 100% by the Xorg. Calculator works -- and the ability to refer to "pi" was a nice "Easter egg" -- but the rest of the GUI becomes "sticky". For example, scrolling through or typing into a gvim window my fingers manage to outpace the computer's reaction...

If either kill the wrapper (and the calculator with it) or "humanely" remove the calculator from the panel, things go back to normal. Removing/readding other plugins does not have this effect...
