White Screen on Rotate

When I select the object in the layer named “Mesh Reduce”, I get a fatal error with white screen. I have to stop the program and relaunch. Happens every time. It first started when I tried to rotate the object, and then got worse.


Does not cause problems for me using Version 6 SR5 (6.5.18132.5131, 5/12/2018)

My guess is your experience is hardware related. Someone more knowledgeable about Rhino and hardware issues is needed.

Must be hardware. Tried on my other machine and no problem.
