Rendered or Artic visualization "cutting" solids

Rhino

Hello there, i have a small visualization issue. in rendered or artic, while i have active the layer of a big terrain mesh, the perspective viewport “cuts” one of the solids in the foregroudn. turning off the layer with the terrain mesh, the visualization resumes as always not “cutting” the object.

i upload some snapshots of the issue, can you help me restoring the standard visualization with the terrain active?

hi @The_G to debug this we really need a file. Also can you run _SystemInfo and post back the results?
If confidential or too big or both, you can upload it here
