When a transparent object in x6 (A) is behind a solid object (C) with another transparent object overlapping and in front (E), there are white lines appearing in the overlaps. A basic example is below. A is at back, E at front of order. Lines from A are showing through C where E is overlapping. B and D are there to also show problem. Is there anything to stop this? It doesn't happen in CorelDraw version Seven (yes, 7). Is this a problem with X6?
Set the view to normal. If the lines vanish, it is an anti-aliasing artifact. Export as raster with anti-aliasing disabled will work. But many on here grip that they want it to work with anti-aliasing turned on. A valid complaint. If this is the problem and you can live with anti-aliasing turned off, no problem. If you want anti-aliasing, only thing I can think of is export with it off, import, export again with it on.
