Post Processing Stack broken with Multi Camera setup since upgrade to 2019

Here is what it looks like in Unity 2018:


Here is what it looks like since I upgraded to 2019 (exact same scene, angle and settings):


Post processing is configured on the main camera, when I open the inventory it activates a second camera to render the UI on top by having it's clear flag set to "Depth only".

This works fine in 2018 but somehow in 2019 when the inventory cam is active it completely strips the post process from the main cam.

Please help!

 

Oh yeah! I figured it out. It is indeed a change in 2019 see this bug report for more info:

All I had to do to get the behavior from 2018 back was to uncheck "direct to camera" in the post process layer of the main cam.

Here is a screenshot:
