This sounds like a change of behavour with the new MCU version that has
nothing to do with GM. There are three reasons why I think this would be
the case:

1) You changed the MCU, and the behaviour changed. GM did not change. So
why do you think this is a GM problem?

2) The endpoint has no control over the video being sent to it - it can
only display what the MCU sends. 

3) The new behaviour (video following the current speaker) sounds like a
plausible mode for an MCU to use. I suspect there is a mode somewhere in
the MCU that switches between this new behaviour and the old behaviour.

Sounds good.
