Today, I "round-tripped" a file from MoI to Rhino 4.0 and back. In Rhino I added a layer, a light, a texture, maybe some viewport stuff. When saving the model in Rhino I chose v4 format... (MoI apparently saved it originally as v3?).
After bringing the file back to MoI, simply pointing the cursor to various places in a viewport causes the display artifacts you can view in the attached jpg. The extraneous triangles sometimes appear in a viewport different from the one with the cursor. Sometimes pointing to an object causes them. Sometimes pointing to an empty part of the viewport causes them. Oddly enough I have a screen shot from the pre-release Rhino v1 days showing the very same sort of artifact.
Both v3 and v4 model files are attached.
