Post processing materials

While using the most recent oculus fork of the UE5.4.4 or possibly any other version... Has anyone managed to get post processing materials to work. Even a simple as setting PostprocessInput0 straight to the emissive color or using any other shader will results into one of these: Turning the right eye black / right eye becomes a copy of the left eye / both eyes will become distorted & warped / only right eye becomes distorted & warped.

- Everything looks normal in the android vulkan preview.

- I think I have tested every possible combination of project settings and device profile settings but I have not found anything that would help. The most important settings ofc are the basic mobile HDR, mobile multiview, forward & deferred shading and anti aliasing... I tried all of them.
