I've had this happen too. For me, disabling a continuously-fading cursor plugin stopped most of my troubles with high CPU. Still kind of ridiculous that to animate the color on a few dozen pixels constantly took so much CPU in 2015, but I'm guessing it was forcing redraws or something. Note that this was on an rMBP with integrated graphics if that matters.
