25-50% CPU usage when idle? I'm running ubuntu 17.04 with kodi krypton and when I simply open kodi and leave it my computer fans come on really loud. In system monitor it shows very low cpu usage, but when I type

    ps aux | grep kodi

it'll show 25-50% cpu usage. I'm running an i7-7700 HQ, and I don't see any good reason to have that much cpu usage. Any ideas on what's causing this?
