Hair display in particle edit

Hair display is very bad in particle edit

My guess is that this is simply a remnant from 2.79.

Particle edit for grooming its not the best looking thing, but shouldn’t show a black block.
By the way if that grooming in the first image of the post are all guides, those are a lot of guide for that shape.

it’s only guides
