What doesn't happen? I'm not sure if you're supposed to get the blurred background for free when using menu item views, but it sounds like a reasonable expectation if you're drawing something that's not opaque. You are drawing non-opaque images, right? Please file a bug report / enhancement request if you feel that the menu item view drawing should work differently:

It might not be as bad as it sounds. Using CGWindowListCreateImage() + kCGWindowListOptionOnScreenBelowWindow could be all that you need. This API is pretty accessible and easy to use. I would expect for you to be able to get something working in a couple of hours. You should be able to get the window of the menu from the view when it's asked to draw. Not sure if there's anything in the timing of the display of the menu view that would make this more difficult than it appears.
