One more tip: Void to use clip-path at all if you can. This is one of the worst scenarios a player should face. It has to generate a path, save it somewhere a background, Then compare every of the backgound/foreground pixel by pixel to see if it is in/out the clip then to decide if it need to paint or not. On your case; Because the clip path is at the background it's even worse
