How to scroll NSScrollView with no animation?

Question

When I scroll a NSScrollView using scrollToVisible or scroll(_:) method, I see they are slightly animated.

How to eliminate these animations?

Answer 1

Just adjust clip view's bounding origin like this.

(superview as! NSClipView).bounds.origin = f.origin

This brings absolutely no animation, and you gonna see no stuttering.

Here's another sample how other people are using it.
