I was playing around with vector brushes and want to create a quick churro style brush. Basically, it's a rounded rectangle [capsule] with some content. Oddly both the texture intensity brush and the texture image brush show a step on the right hand side [more visible in the curved than the straight line version]. It shows up in the brush editing popup as soon as I set the ends. Strange enough the 'repeat' setting shows it right and it just seems to happen in the stretched with defined ends. Rounded and square cap show the 'step' while the butt cap shows the smooth curve but a very squashed version of the ends.
