I’m drawing polylines and adding points to them dynamically in a 2D map. At one area, the polylines overlay on top of eachother for a period of points. When zoomed in, the lines display as expected but when zooming past a certain level an artifact is displayed whose appearance keeps changing as the zoom finalizes (finishes updating the map). The artifact is most noticeable when using a line width greater than 1 (in the attachment a value of 5). Any ideas on what is causing this artifact or how to get rid of it?
