Geek window bugging

Hello, I am using WhatPulse on my Mac OS X 10.10.3 and I’m getting a bug with my geek window. The window just duplicate itself and I can’t move/hide the duplicate. The duplicate doesn’t update itself either.

Is this a bug? If so, is there a way to prevent it from happening?

I’ve seen this a few times when you change the screen config (resolution or amount of screens), usually double clicking removes it. If not, just restart the client and it’ll be gone.
