Rhino- objects not displaying correctly

Hi,

The objects are not displaying correctly in my rhino. As you can see from the screenshot below, the tables and people are showing up in the view even they are behind the orange plane. Any solution? thanks.

Maybe ClearDrawOrder helps?

an image only tells us so much, we could be dealing with ghosted view, setobjectdisplaymode set to ghosted on some parts, maybe its a driver issue we might never know,

if you post a file or a portion of it people can actually have a look why its happening.

An example would help here, but I am going to guess this is an object that is very far away from these objects. So essentially the Video card Z-buffer is starting to break down and the front nad back hiding is not working well. This is normally a large part of a site or a few city blocks around a smaller area that is being looked at.

Like the others have stated an example file and the results of a Rhino SystemInfo command would help.
