Summary: Attempting to use core animation on a view that's inside of a flipped NSScrollView and flipped documentView causes core animation issues. I've attached a zip file with two xcode projects. One illustrating the issue. The other illustrating a strange way to fix the issue. Steps to Reproduce: 1. Create a new Document Based Application 2. Add a scroll view to the window 3. Create subclasses and override isFlipped for NSScrollView and the documentView. 4. Add an NSImageView to the scroll view - set some kind of image on it. 5. Try to fade out the image with it's animator.alphaValue Expected Results: The image properly fades out. Actual Results: The image appears to break up and not render properly.
