The latest 1.5.0 builds have done a great job on diminishing this effect when I put round sprite on half or full. Unfortunately, I get green vertical lines that I can't fix with TC Offset. If I put texture filtering o billinear (forced), they are no longe there, but there's a visible misalignment were the lines were supposed to appear. It's almost there!
