We use 3.1.6 on MacOS
We've noticed that when we move to a video in the live presentation, it will blank to the desktop and then a few seconds later the video will pop up on the screen and play. It will begin playing, so we can hear audio--we just don't see the video on the screen. We've tried pre-loading it in the cache before the service starts by clicking into it and letting it play for a bit before stopping it but this hasn't helped.
