Jibri recording not focusing on the speaker 80% of the time

I’m having an issue where Jibri recordings are working, but rarely focused on the actual speaker. I didn’t notice this in my first few weeks of using my Jibri setup, but lately it’s been very noticeable and recordings look almost unusable - 80% of the time the speaker isn’t even visible, but instead you see video of someone on mute just staring at the screen.

Any idea why this might be? Have I configured something wrong, or is there some kind of setting to tune?
