Hi, the css animation of the svg:circle looks weird. It seems that the size of the bbox does not follow the size of the circle itself. As a result the circle from time to time is cut at borders. I have not faced this problem with other browsers. The problems seems to appear on Windows 7/10 only. On Mac this looks better. https://jsfiddle.net/j974Lkq8/ https://jsfiddle.net/dnvaw7to/ When I use SVG animation all is fine. https://jsfiddle.net/gex5rL3o/ Regards, Maciej
