Resolved 2019.3.10f1 - Camera Stacking Working For Anyone ?

As the title suggests, I create a new camera, set it to Overlay, set it to render a particular layer I want, and then go the Main Camera ( remove said layer from that camera ) and add it to the stack, BLACK screen...

I'm pretty sure I tested this in earlier release and it was working, now it isn't again ?

EDIT :

Ok, couldn't find this documented anywhere, but apparently the black camera screen is caused by having 'global' anti aliasing switched on in the pipeline asset, turning it off here, and enabling anti aliasing on each of the cameras separately fixes the black screen issue.
