Cinemachine pixel perfect extension stopped working with Pixel Perfect Cam in 2019.3.0b8 ?

In 2019.3.0b7 , the Cinemachine Universal Pixel Perfect extension seemed to be working pretty well.
Since updgrading to 2019.0b8, things seem to be broken:

- when the cinemachine extension is active, the image seems to jump to the reference resolution of the Pixel Perfect Camera, instead of upscaling the output image (so basically showing only a cropped frame)

- the main camera gets locked in X and Y coordinates that have nothing to do with those in the Vcam, which are at (0,0,-10), so in effect not showing what is framed with the Vcam, and impossible to move it

- if the cinemachine pixel perfect extension is removed, the output image is not pixel perfect anymore, even if the Pixel Perfect Camera onthe Main Camera is still active.

Tried all the latest Cinemachine versions without any luck (2.3.4 / preview .3 / preview .4).
Ideas?

 

Found the issue, which seemingly has nothing to do with Cinemachine.

Updating b7 to b8 kills the link to the Scriptable Render Pipeline Settings (URP asset), yet keeps the Pixel Perfect Camera active and the Cinemachine PixelPerfect extension, leading to the results mentioned above.
