Description tomtomtomreportingin 2022-10-08 22:07:06 UTC 
SUMMARY
1-px sharpness brushes don't support changes in spacing.

This is likely because KisPainter::bitBlt (used when Sharpness is enabled + brush is 1px) doesn't seem to account for spacing.

STEPS TO REPRODUCE
1. Select u) Pixel Art brush.
2. Set spacing to max.
3. Paint a stroke.

OBSERVED RESULT
It's a continuous line.

EXPECTED RESULT
A dotted line.

Yeah, we use a different line drawing algorithm there all together.

I can confirm with the Krita Version: 5.2.0-prealpha (git 5c98a72) Appimage with Qt 5.15.7
