Zoom webinar shot sizes changes on active speaker view switch

[tknightfda]

Can't figure this one out. I run Zoom webinars which add graphics to and livestream. We also run slides in a separate window when necessary. Generally we get together with the participants a few days ahead of time to check lighting and framing. So our gallery view looks great, but in the last few webinars Zoom has started changing the shot size to be a wider shot any time the auto switcher moves to them in speaker view. It messes up the framing completely. We can frame for the gallery view or the speaker view. Not both. Any idea how to fix the shot to a specific size?
