Due to an oversight on my part the UI was requesting the autosave image every time there was a new one. This was bad for streaming performance as every 20 seconds the browser would request an image which would cause stuttering due to a spike in network activity.

This was caused by the loading overlay which shows your latest save screenshot while loading. I was not showing this component but it was still be rendered. I'm now using true conditional rendering on this component which eliminates the issue :)
