Tiling artifacts in panoramic rendering UE5

Hi!

I’m currently trying to render out a scene with the Movie Rende Queue Additional Passes plugin which now contains a panoramic renderer feature. However, I’m getting these vignette tiling in the final render:

The settings used inside the panoramic render tab are show here down below:

There isn’t a vignette setting applied in neither the volume or the camera.

Does anyone know how to fix this so that it looks like the one on top?

thanks!
