The situation and the various effects that can be observed are many, varied and complicated. It has to be seen to be fully appreciated. For a layer set to Copy blending mode, if you paint on it with any brush engine, there are artifacts around the brush stroke. If you then toggle the Background layer, it won't come back to visible. If you then turn off the paint layer, you get a white rectangle that is larger than the bounding box of the painted stroke. If you then set the layer blending mode to normal, you get the painted stroke on the white rectangle. Then toggling the Background layer brings it back to visible. Then setting the layer blending mode to Copy gives a different set of behaviours as you toggle the visibility of the two layers in different ways. For a brush preset painting in Copy mode, there are artifacts around the stroke for the Pixel engine brushes and other brush engines but not the Colour Smudge, unless it is used close to the stroke from another brush engine, in which case there are hidden artifacts that are revealed by painting with the Colour Smudge brush preset. For a Filter layer, there are no artifacts when switching from Normal layer blending to Copy Blending. Panting on a filter layer with a brush preset set to Copy mode does give artifacts around the stroke. If the filter layer is then set to Copy blending mode, these artifacts become larger. -- You are receiving this mail because: You are watching all bug changes.
