ZoomGov webinar recording format changed?

We recently recorded "active speaker with shared screen" for a ZoomGov webinar. The active speaker window appears over the top right of the shared screen, obscuring the content (slide titles). Previously the active speaker window appeared to the right of the shared screen and did not obscure the slide content. Is this a new change? Is it a setting? Is there a way to prevent the active speaker from obscuring the shared content? I pant for light, but there is no light.
