Post Processing + Pixel Perfect Camera

Hello there,
I have a bit of a problem with applying post-processing volume on the camera that has the Unity's Pixel Perfect component applied. The problem is that even though all anti-aliasing is turned off the post-processing seems to apply some kind of anti-aliasing to the scene which causes the bluriness of the sprites. Have any of you had some experience with using post-processing for pixel perfect games? Is there some known workaround or the setting that I might have missed? Can the HDR being turned on be the cause?
Cheers

 

you cant even have a camera with the pixel perfect component added to it
