Painting Effect having Dots if moved fast

I am trying to realize a painting effect drawn by the mouse movement. I use the feebacktop and a cirle, similar to how Elburz does it in his tutorial. https://www.youtube.com/watch?v=7SYZKvjnPogThe problem is, that when I move the mouse very fast or have the cirlce quite small I get these dots. I guess it is because of the 60fps framerate of TD. Does anybody have any idea how to fix that problem?

Instead of using a feedback loop, you should go the Chop and sop way. For example, use the input of the mouse and then convert it into sop with the limit sop. Here is an example
