In my app I want to provide text scaling in layer backed NSTextView like Apple's TextEdit. I use analogue of it's ScalingScrollView. Also I need to create some CALayer overlays on self.window.contentView. All is ok until I make [self.window.contentView setWantsLayer:YES].
Before [setWantsLayer:YES]

After [setWantsLayer:YES]

I haven't any ideas how to fix this problem.
