Rendering OSL with CPU retains a haze of a former .exr map used prior.

When I render this OSL https://pastebin.com/tsxjpU7v with GPU it's clean, but with CPU is retains a haze of a former .exr map used prior.

This is render with GPU

This is render with CPU

Seems to be attempting to render this current exr

along with this previously used exr

Works fine in MAX, so this appears to be a MtoA specific cache glitch.
