Presets that use the Color Mix option set to Fuzzy are producing sharp edged artifacts when the Brush is set to wash mode. In Buildup Mode the Brush looks as expected. Reproducible: Always

Hi, Can you also add a preset that can be used to reproduce?
Created attachment 83580 [details] Soft Tip, Wash-Mode, Fuzzy Scatter, Fuzzy Colormix Created from the Default Airbrush; changed Opacity (0,2->1,0), activated scatter fuzzy, activated colormix fuzzy, changed spacing (20->10) and quality (1->3)
I can confirm. I'm not sure how fixable it is, though...
This is ancient but according to boud it's still relevant. I'll bump it so it won't show as the oldest bug report that's open.
Some updates as im close to fixing this: This can be exagerated by picking a light colored foreground color and a dark colored background color. It only happens in autoBrush The artifacts are triggered on a strong change in Mix Strenght, which makes fuzzy dab the perfect mode to trigger it.
Created attachment 120465 [details] Artificial edges more visible. Value set to pressure modifier. Both stroke blobs were made in a single stroke. On the left: the first dab is made with almost no pressure and the surounding dabas are made at strong pressure. Notice the edge is marked for the original shape if there is a change in the sensor value. On the right, eventually drawing over and over will remove the artifact as it only occurs on the "alpha" boundaries of the current stroke.
