WebcamSubscriber positioning and sizing

[Former Community Member]

I am using 2 WebcamSubcribers in a ConnectSessionContainer.  The first WebcamSubscriber seems to be positioned and sized correctly, then when I add another the size and position changes, and I'm not sure why.  The first image below is with one WebcamSubscriber, and the second image is after the second WebcamSubscriber gets started. Also, top-left both WebcamSubscribers should be positioned at 20,100, and that's not happening either.

The code I am using is below both images.

Thanks!
