When I keyframe the scale of a vector based layer the graphics has a unwanted "grow/shrink waving" effect of the edges of the graphic lines. Is there a workaround to avoid this? Pre-compsing the layer doesn't help.
Try adding a slight Gaussian blur. About enough that you notice it if you toggle it on and off, but wouldn't think anything of it if you happened upon it. (fwiw, I add a slight blur to all my vector graphics and it makes a HUGE difference!)
