Where is y?

I admit I have lots of strange problem ? :sweat_smile:
Therefore, who can tell me the reason for this picture ? :scream:
It sometimes happened.

Hi Steven,

Can you tell us what your system are you running what version of Rhino on?
Windows version?
Rhino version?

First I would at least try to update Rhino to the latest version.
Update your Video driver
Run Windows Updates.


Version 5 SR7 64-bit
(5.7.31213.18395, 2013/12/13)
OS:Win 8.1
Geforce 740M

Your Rhino version is out of date, try updating Rhino first and report back if it does not solve the problem.
