I´m facing a problem using Rhino 5 on Windows 7 on a Mac with Parallels Desktop 10 (Mac OS 10.10.4).
If Rhino is running and I switch to Mac OS and back to Windows again, the Rhino viewports (only them!) turn black. Not always but most of the time (it seems almost random).
So far I couldn´t find any solution working out and as my flatmate got the same issue it must be a common problem. So I hope you guys can help me out. Looking forward to any response.
Thanks a lot!!
