While you may have solved your problem, your general approach is not one that would be recommended – CALayers are not meant to be drawn into a context, but rather added to a layer tree to be rendered by the system. For what you are doing you would likely have less issue and better performance drawing your shadows with AppKit or CoreGraphics directly instead of using CoreAnimation as an intermediary.
