let's say I created a double color brush (using 'unlean brush', and loading it with 2nd color by driving it at a border of a blob of second color). Let's say red is at the top of the brush, and green at the bottom. Now I want to paint left to right, lift the brush up, next right to left, lift the brush, left to right , lift the brush, and so on. I expect the red to remain always at the top and green always at the bottom. But sometimes the colors get switched, ie red ends up at the bottom and green at the top. Not a natural behavior I would expect from paiting back and forth with a conventional brush. How can I stop swapping the colors? thanks
p.s. Galaxy Note 10.1 2014, which doesnt support tilt of the stylus
