Display problem grasshopper preview in rhino

Hello,
aaah this drives me crazy! I have a problem with Grasshopper and the preview in Rhino. I didn't find sth in the discussions. I work with Rhino 5 and GH 08.0066. If I activate for example any element in rhino that is next to the previewed GH stuff it fully appears but without it looks like the one beneath. Has someone an idea? Thanks for any help!

It's hard to see what's going on, but is it a near/far clipping plane bug? I.e. is everything closer than X units to the camera invisible?

Reason for this could be that the bounding boxes or clipping boxes for the geometry are not correctly computed. But I need to know how they are created and which object is drawing them (mesh parameter, geometry parameter, script component, ...?)

Hey David,
me again, the same error again, here you can see the screencaps and I attached my files. The original Def is made by 3D-dreaming, I rebuild it:
one with the error:here I activated the surface and then it is normal / visible:

I can't repeat it. It's clearly a clipping problem though. Do you have any other plugins loaded that draw stuff in the viewports?

No it is only rhino and Grasshopper. No other plugin is running.

This has happened to me before when using very wide view angles, I believe I just focus on the GH object with the magnifying glass in grasshoppers radial menu and it fixes it.

I restarted my PC, tried it with the magnifying glass but no, no way, still this clipping problem! Maybe I have to reinstall it or I will first try rhino 4 if it is still the same.

Thanks for your proposal!

Thanks for oyur help!

Same for me. 5's display is shot, 4 works fine.

Did nothing but regular beta updates. Last time I ran GH on this PC was April. Not sure if this was rhino 4 or 5 but everything worked fine back then.

This is a clean new file with nothing but two points an the preview geometry. Clipping obviously inludes the two rhino points only.
