Preview Issue

Hi, I have a weird issue: Rhino preview disappears when Grasshopper preview is on, at the same time the “green” preview of only selected geometries in GH is not working.
What I’m missing?

I’ve noticed that the issue is due to a red component in gh, if I deactivate it the preview works fine

Hi -

Is that a standard component? Does it work fine in a different Grasshopper definition? Can you post a gh file that is giving you problems?
