I admit I have lots of strange problem ?
Therefore, who can tell me the reason for this picture ?
It sometimes happened.
Hi Steven,
Can you tell us what your system are you running what version of Rhino on?
Windows version?
Rhino version?
VideoCard?
First I would at least try to update Rhino to the latest version.
Update your Video driver
Run Windows Updates.

Your Rhino version is out of date, try updating Rhino first and report back if it does not solve the problem.
