Thanks for your consideration , I am using on PC Kodi , which is Extra super fast compare to Shield or android , Some time Kodi background addons make CPU Usage 100%, that cause to load widget slow and we blame skin mostly .

Yes mine does that too for some reason. CPU goes to 30% makes my Fan's kick on. I just restart Kodi usually fixes it.

me too i noticed this and sometimes it stays for hours like this and goes away on its own.
My Cpu also goes to 100% and it's a mac mini 2014 with a 2,6 GHz Dual-Core Intel Core i5 

I suspect skin helper service behind this or a bug in the skin.

100% skin helper. It's mentioned in some other threads.
