Rendering

Hi,
I am working on a scene using Unreal 5.7 with FluidFlux however when I am rendering via movie render queue I am getting a lot of artifacts. My camera is positioned underneath the water surface so we are underwater and looking slightly up through the surface of the water where there are static meshes floating above the water.

In the viewport it looks fine :

however once rendered via movie render queue the artifacts appear :

for lighting I am using Ultra Dynamic Sky and my settings in the post process volume are default with Lumen set for GI and Reflections.

I did many tests and so far the only workaround I found is to disable Lumen on GI and Reflections, which does change the look quite a bit thats why I would like to find another solution.

those are my settings in the movie render queue:
( I did also run tests without anti-aliasing but the artifacts are still there )
