I am currently having an issue with grasshopper where the line | plane intersection component is causing all geometry to disappear from my perspective view.
The component in question:
bug line plane.gh
I believe it might be an issue where the lines are parallel to the plane.
If I disable the component, the geometry reappears.

Another user reporting the same issue:
Is the intersection between the line and the plane really far away?
Unfortunately the line plane is parallel to the plane or close to it. It either results in null or a very large t value.
Yeah I’ve noticed before that sometimes geometry really far away causes the display to go haywire. I can’t remember whether the 4View command fixed it or not.
If this is still happening in Rhino 7 we’ll need to look into it and fix it.
This is Rhino 7 beta:

I’m currently replacing the line plane intersection component with the following python script so that I can view my work in the meantime.
ndotu = x.Direction*y.Normal
if abs(ndotu) > 0.01:
w = x.From - y.Origin
si = -y.Normal.Multiply(y.Normal, w) / ndotu
a = si
b = w + si * x.Direction + y.Origin
a = None
b = None
