Yeah, the strangness was random depending on how the items were placed and rotated, it only happened on occaision, and not always to the same item. What would happen, was that the line segment of a triangle side, would be 2 pixels wide at it's center region, but only 1 pixel near it's end points. Or, there might be a slight stair-stepping effect if the angle was right. Maybe it's my video card?
