I looked that on the cubic generalised Mandelbrot fc(z)=z^3+2,5i*z^2+c at a segment on line exists an infinity number of kompassbrot points (like -1,3685948042...+0i for Mandelbrot set fc(z)=z^3+2,5z^2+c) except Missiurecz points.
Details in the picture:
This line segment don't contain neither minibrots.

If approximating on Mandelbrot set fc(z)=z^3+(2,51+0,01i)*z^2+c the line become a dust with minibrots in lateral (watch another picture)
