And no I don't think we ever had much chance of catching this in early testing, because:
* I didn't know some of the code being moved is only used on Nvidia.
* Even after I started testing Nvidia in response to this bug and developing a fix, the problem is very subtle for me. Almost imperceptible other than the log messages. So I would not have noticed it as a bug myself.
* No one on the team who does use Nvidia has mentioned it to me yet.
