I have a problem with masks and soft edges fills to make shadows, in the gradient edge it appears some white pixels at the mask edge (you can check the image of the problem). This not happens with plain fills.
There is the file: https://www.dropbox.com/s/gcbdhevdn4pvl ... .anme?dl=0
Somebody know how to fix this? thanks for your help
