Implementing it did not help. Not a surprise since my view doesn't change

Or you can try specifying NSTrackingInVisibleRect to take care of much tedium

I have a view for which I am adding a tracking area so that I can update the

The tracking area is being registered thusly:

In a test case of about 1500 items, scrolling gets unacceptably choppy. I've

While scrolling, _updateTrackingAreas is called

Interface Builder is a fundamental part
