MagicMirror2 fade animation requires 99% of the CPU?

Help my MagicMirror2 is verry laggy everytime is does (well… tries) an animation.
I had this problem before and decided to do a fresh Raspbarian install, same problem. This is so frustrating, uuugh.
I use Raspberry Pi 3b, 16G SD card.

Please help me, thanks :)
