What OpenGL driver does your Windows machine have?
Hallo Mr. Graham Dunnett,
Thanks for replying . 
Here i attached the open gl and video card specification.
When you click the “Check for updated drivers” what happens? I’m not sure many Unity users have a great deal of experience running OpenGL under Windows.
I’ve got similar problem in 4.6.5:
when launching the program with -force-opengl option, it runs normally; then if I use Alt+Tab to switch to another window, and then switch back, the program window shows all black.
Has this bug been solved please?
