Hi guys, I'm drawing a chart with roassal2 and just discovered that lines are not being drawn exactly as expected. Maybe this is a known problem? I'm running on a few months old pharo4beta image, in linux. Here I attach a screenshot corresponding to the code below. There are more evident examples but this one is easier to debug as it is a straight line made of many segments (zooming a bit you'll see the thin reference line and notice the blue line "bends"). Thanks for reading!
