Unfortunately, for me the CPU usage problem sooner or later reappears. According to your explanation, it is rather something that the skin has to fix?

EDIT:
For me AS is completely unusable with Aeon Nox Silvio. As soon as ANY media playback starts, the cpu usage goes up and never down again. I completely disabled the addon for now.

I'd be really interested to see debug logs.  I can't figure out how AS would be spiking things when playing media, especially video, which AS would consider playing video an "idle" event.
