CPU usage of "hide menu items" constantly 25-50% (!!!)

Hi, the CPU usage of "hide menu items" app is constantly at 25-50% of one core of my 8 core system. What is going on?
This app is so buggy, if it isn't fixed soon, I'll deinstall everything and leave Parallels completely.
Thank you.

 

Now, it normalized a bit and I can't see this behavior for the moment, lets see if it works now.
