HDR disabling custom post process

Hey guys!
I’m having a issue where, when I enable HDR in my camera the outline effect, created by following the steps from the link below, it stops rendering.

Without HDR:

With HDR:

I also receive the error “GL.End requires material.SetPass before!”

The code I’m using is from this page: Unity Shaderlab: Object Outlines | Will Weissman - Game Developer

Try to move your effect on top of the Post Processing Stack in inspector

I tried, but it flips the Y axis of the view

Change y axis scale of the camera to -1
