PP Stack with multiple cameras in 2019 issue

I'm having an issue and I can't figure out if it's me or Unity not doing something right. I've tried 2019.1 and the beta/alphas for .2 and .3. Unity 2018 renders everything the way I expected it would. I'm using the default render pipeline.

I have a scene with 2 cameras (fgCam and BgCam)

The problem is when fgCam has it's Post Processing Layer component enabled it's blocks my bgCam rendering anything. If I disable that component both cameras render and the bgCam's PP effects render fine. Does 2

fgCam has some objects on the fg layer, uses fgVolume (global) which uses fgProfile (which just adds some color grading). The camera is set to "Don't Clear".
bgCam has some objects on the bg layer, uses bgVolume (global again) which uses the bgProfile (add some DoF and vignette).

If anyone knows how to get both cameras to render that would be great.

Some pics if none of that made sense.
