Brush hardness blur is slow

Description
How demonstrate the freezing:
- Use two kind of brushes, raster and parametric.
- Begins paint a line with the Paintbrush (recommended with Ctrl+Shift) with the parametric brush with a linear curve on hardness paint dynamic;
- After, paint another line with Paintbrush (is very recommended with Ctrl+Shift) using the same linear curve on hardness paint dynamic (is necessary circa 150 seconds in my computer*);
- Modify the paint dynamic curve from linear to a fast curve, see my figure, and apply again the brushes (parametric and after the raster brush). Is necessary circa 100 seconds to finish the stroke with raster brush.
- I have a final test with a slow curve to hardness on paint dynamics, see my figure. In this case was necessary also 150 seconds as the linear curve.
On Tool Options were used: Opacity: 100% Size: 50 pixels Hardness: as the default of parametric = 100% Force: 50%
