Is there a way that I can make a transparent and rounded NSBox with a blurred background?

I have tried to use CA Background Filters to achieve this, but it seems that the part of the background which is blurred is not rounded, as you can see here:

Is there a way that I can somehow prevent the blurred background from overflowing the border?

I was able to finally fix this by wrapping my NSBox with an NSView that had a cornerRadius property, and then applying the CA filter to that NSView.
