Success, I now have rpisurv v3 running under Bullseye on a RPi 3B v1.2, it is mostly working as I wanted, that's 2x2 rotating x2 from my 8 cameras' rtsp NVR feeds. I use the sub-stream feeds which is acceptable.
What brought success was editing the general.yml file to stop opportunistic caching, ie enable_opportunistic_caching_next_screen: False.
Earlier I got a sense that caching was the issue here, altering the GPU memory allocation did not work.

I suppose the only downside currently is at the 2x2 display changeover, I briefly see a 2x2 matrix of "connecting" messages. Caching seems to rob resources too early that the first 2x2 screen still needs for display.
