User Scene Texture gets cutoff in VR for Right Eye

Hi Everyone

I have a problem with User Scene Textures in a VR Setup and I would hugely appreciate some help.
This is the guide I am roughly trying to follow:

I’ve reduced everything in the guide to two steps: Downsample and Apply (as in display downsampled texture on the screen).
However no matter what I do I am always missing the right eye and all I am getting is a stretched version of the right most pixel

I’ve tried offsetting the UVs in all crazy directions, used frac(), nothing helps.
Is that blit unable to handle both eyes?

I am really lost on this, please help.
What am I doing wrong?
