Rendering with progressive CUDA renders first frame twice

Yes it should work fine in both cases.

Finally got a chance to test this. I am still seeing issues when trying to use CUDA progressive mode via Deadline. The shot camera keeps jumping back to it's start frame, objects are in the wrong world space etc. It feels like the GPU is using cached data when it should be reading new data or something.
In my case I have a few animated alembic files including an animated camera.
Even in the interactive session I get incorrect object positions at times until I change the geo a little, then it snaps back to where it should be. Definitely feels like an incorrect cache.
