bad line tapering in krita in linux

SUMMARY
***


STEPS TO REPRODUCE
1. Open krita in the latest linux mint or ubuntu
2. switch Brush smothing to stabilizer (at around 50) With delay, finish-line, and sensors checked off.
3. With a big (around 50-60 pixels) ink brush, do a quick stroke.


OBSERVED RESULT
Line tapering is not smooth, instead a sort of step ladder is created.

EXPECTED RESULT
Line tapering is smooth and controlled, tapering to a fine point uniformly.

Hi, Romero!

Could you please try disable "Stabiliser" and enable "Basic Smoothing" instead? Stabilizer is not supposed to be used for quick strokes. Also, try enabling "Stabilize Sensors" checkbox in the its options.
