Visualisation bug (triangular mess)

Hey all!
Does anyone get this kind of weird geometry when changing some input parameters i a grasshopper definition?
The actual geometry is fine, since it bakes right.

What it does in this case, it connects one piece (a mesh) to another piece with those pesky triangles.


Thanks for your interest!

still having this pesky bug…

Please post a Grasshopper definition so that someone can try to reproduce this.
