I've been following this thread. I have a computer science background, I know what anti-aliasing is from a university course back in 1986. I've been using AD for about a year. I am using symbols to make my vector design symmetrical at the point of reflection. It works beautifully, except that at the join there is a fine line appears between the two reflected clipping rectangles. The rectangles are perfectly placed, using snapping, so it looks like anti-aliasing. I go to the layer options Cog and force anti-aliasing OFF and the line on the screen disappears. But then I can no longer export as PNG without horrible pixelated curves. If I leave it ON or set to Inherit, the fine line appears in the exported PNG.
Is there a fix?
