OK, I'm back in the office and checked. Our pause function is complicated, but essentially it boils down to:
- Stop updating everything (timescale 0 or whatever)
- DISABLE cameras. (this is the important one)
The validator is checking for "app must not submit frames", so if you do `camera.enabled = false` or `camera.gameObject.SetActive(false)` then that camera will stop rendering frames and the validator won't see any!
afaict, the validator can't really tell what's happening with input, so you just have to ensure manually that your app isn't doing anything whilst it's in this "pause" state.
