That's really surprising. I have no problems on my win machine which I guess is why I missed it.

Is it the same problem even if you run it in backgorund? Have some listeners that will pause the youtube video when that happens (which should minimize CPU)

For me the high CPU usage seems to happen because of the video background. As soon as I remove the <div class="video-background"></div> the CPU usage drops to normal on my MacBook Pro (with integrated GPU)
