Hi Paul,
Thanks for reaching out!
We've frozen development for Replay 360 so no enhancements are currently in the works. If you're having trouble recording your screen even after reducing the scaling down to 100%, please open a case with our support team here so we can check what's happening.
Alternatively, Storyline 360 also has a screen recording feature that you can use if you need to make a quick recording of your screen. Just make sure to match the screen resolution/recording area with your slide size to get the best quality possible in the recording.
