I tried using scrollToPoint last night. For the point to scroll to I used 0,[[terminalDisplayScrollView contentView] documentRect].size.height

However this resulted in flickering every time the view was updated. I turned on Quartz Debug and noticed that every other time the view refreshed it blanked out to white, then on the next refresh it would redraw correctly.

This will not work, because the height of the text view is not correct until the text is laid out. The real problem, as I said, is that you are invalidating the entire layout every time. That's what's causing your flickering, too.
