Confirmed. We are looking into this. Recommend not using the NVIDIA 375.27.12 driver (stay on 375.27.10) until we can figure out what regressed.
We got word from NVIDIA that they have found the problem and are working on a new driver release. Thanks for the report!
We released new drivers (375.27.13) that should address this issue.
I can confirm that the new drivers fix this error on my machine. I also have the feeling that the new driver reduces the perceived delay/distortion on rotational transformation a bit. I see the distortions mainly at the edges of the view so it could be linked to a difference in running the lense distortion shader?
Nothing extracted yet.

Steps for reproducing this issue:
Destinations works ok but does sometimes show the visually also broken SteamVR loading environment. A Unity test build shows the same visual glitches in the Unity loading screen. After the scene has been loaded it renders correctly.
