I am also running the latest driver on my 780M on Windows 10. I am having the same issue with a blue tint appearing over everything during the benchmark. However, I found this only happens when running the DX12 build. Running the other DX version (not sure what it is) looks fine.
Edit: So i got DX12 to go non-blue by setting the preset to low. Alternatively, I also got the non-DX12 build to display properly on most settings, but has the blue issue on certain others. So...having a tough time pinpointing the cause other than it seems to be more prevalent in DX12.
Edit2: So...just ran a benchmark in the non-DX12 build and there was an obnoxious PINK tint on the screen this time. I backed out of the benchmark, didn't change anything, and ran it again, and it displayed fine. So far it appears to be almost completely random.
