I have a big peoblem. It started to happen few weeks ago, which makes me think that it is because of the update to Windows 10. (Also I had trouble with Photoshop.)
The problem is, I can render all OK with my CPU. It's an i5 7400. But when I try to render with my GPU I have really annoying holes in my mesh.

Please, if somone knows what to do, tell me how to fix this issue.
