This is wrong. The designated initializer for NSView is -initWithFrame:

It is the same size, it's just not in the right place, is my guess.
Use the correct initializer and pass it the frame you want up front, then just add the subview. There's also no reason to call -displayRectIgnoringOpacity, the view will get drawn on the next cycle as normal.
