When applying a filter, it seems it does not care about alpha values in the image and treats 0 as if it was 1. How does anyone works around this when applying effects to selected image parts that are isolated in individual layers? Even when selecting and trying to apply filter to selection, more than the selection seems to be taken as input for the filter. As a new user I would like to know how to work with this in general or if this maybe is changed in v4, thanks.
