magically enough, my memory consumption and performance has suddenly improved. XD

however I do have another question, which is does anyone else have some seriously awful scroll behavior when using touchpad gestures on a Mac?

Yes :(

it feels like it’s scrolling on a character level, instead of smooth scrolling?

and it is quite uncontrollable, the momentum goes all wacky
