I'm experimenting with both the X3 and the 2019 versions of Painter. Something weird is goin' on. When I release the mouse button after completing a stroke, the stroke starts to blur and fog.
Almost as if I was painting with watercolor and I was applying paint to a wet piece of paper. In other words, the paint is blooming.
Don't know why or how to fix this.
Actually it only seems to do that with a certain brush. Maybe that's what it's supposed to look like.
You're probably right! I bet it's one of the fancy runny watercolour brushes.
