Is this in Rhino 6?
Did that just start happening whereas it used to be fine for several months? If so, what was changed?
Could you post the output of the Rhino SystemInfo command?

Hello - see if un-checking the setting for ‘GPU tessellation’ in Options > View > OpenGL helps.

just had a second tech case where this behavior was cured by unchecking gpu tessellation.
