Plasmaoid Calender eat CPU

Plasma have had some memory-problems, but now in KDE4.22 it seem memory-stable.
Now the problem has been CPU-usage.

Plasma has been using aprox 50% CPU constantly. Reboot does not solve this, so i tried to remove Plasmaoids one by one, and now i found out its the Calender.
I really like the calender and want to use it on desktop, but there is some problem with this that eat CPU.
Does it exist other calender-plasmaoid that is better?
