Does your VM have 3D acceleration enabled? If so, have you disabled Transparency settings disabled in Windows 10?

Yes, 3D acceleration is enabled. The transparentcy in Windows 10 is disabled, for better performance.

So, I found the solution for this problem.
I must disable the 3D support for the VM.

It is also the solution for viewtopic.php?f=2&t=107184.
