Bug ID: 452811
Summary: Issue with certain MyPaint brushes
Product: krita
Version: 5.0.5
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Brush engines

Created attachment 148273
--> https://bugs.kde.org/attachment.cgi?id=148273&action=edit
here's a screenshot of the affected brushes, strokes made with "stabilizer"
mode, sample count 70
SUMMARY
***
The Pencil 2B and Ink Pen brushes in the MyPaint bundle produce rather
polygonal strokes when using the "Stabilizer" mode even at the lowest "Sample
Count" values.
"Basic" and "Weighted" smoothing modes are unaffected.
This seems to happen regardless of Input device, giving the same result with
tablet or mouse.
This seems to happen with the default brush settings of said presets.
However, changing the affected brushes' Slow Tracking parameter to 0 seems to
apparently fix the issue, although the Ink Pen brush then *suffers a side
effect* from this workaround, producing a repetitive pattern all across a
stroke
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.

***
STEPS TO REPRODUCE
1. Select Pencil 2b (mypaint) or Ink Pen (mypaint) brush
2. Select Stabilizer smoothing mode with a minimum to medium Sample Count value
3. Try making round shapes like spirals or circles, using swift motions
OBSERVED RESULT
Resulting strokes look oddly polygonal
EXPECTED RESULT
Smooth and round strokes, like every other brush does under the same
circumstances
