Make sure your image is in 16 or 32-bit mode, under image->precision. When i tried, i found i got blotchiness in some images, as if the filter was running at a lower resolution and pixellated things. It might be worth a bug report, as clearly we want the filter to be useful :) Or if you discover an answer, please let us know.
