STEPS TO REPRODUCE

1. Select the brush "u) Pixel Art"
2. Set the brush size to be strictly less than 2 pixels
3. In the brush editor set Opacity to be controlled by distance, and make sure that the parameter "Sharpness" is activated
4. Draw with the brush

OBSERVED RESULT
The line has constant opacity at 100%

EXPECTED RESULT
The opacity should vary with distance
