[VR] The post process layer causes the left eye to be white

HI~
I am testing the effect of VR projects 3.0.3 Post process,
simply set up the post process layer to the main camera,
but found that the left eye would be white.
my situation:
Unity version : 2018.4.16f1
Post process version: 3.0.3
Only set the postprocess layer on the camera

does any got this problem??!

this is my frame debug
You can see that copystd got a white texture

I had a similar problem. I moved the post-processing layer from the central eye anchor to the ovrcamera rig and it was solved.
