So far the only solution I've come across is setting the smoothing to at least 1%. This eliminates the dot that appears at the end of a brush stroke when brush opacity/shape dynamics is controlled by pen pressure.
Hopefully Adobe will fix this soon. It's inconvenient to set the smoothing for every brush you switch between.
I hope so. In the previous update the problem was solved by deactivating the "build up" option. But now there is no solution. In my case, the brushes that I have the most problems are the ones with size variation and setting the minimum value to 1% does not seem to work. 😞
