Airbrush draws artifacts

I think it's a bug...
#1

If the brush’s radius is large enough, it will draw a straight line pattern at the top and left part of where we’re drawing on.

Reproduce:

  1. Single pixel brush
  2. Select Spray Paint tool
  3. Select Airbrush
  4. Set a large radius
  5. Draw

airbrush has artifacts
