核心动画视图有时不显示

I'm working on a Cocoa project using Core Animation and I've got a custom view that is displayed in two windows. It always shows up in one window, but sometimes does not show up in the other window when I start up the application. So far as I can tell, it is completely random. Here is the code I call when the view is initialized. It gets to this code whether or not the view appears.I'm working on a Cocoa project using Core Anima
