Glass material behaving different in render

Hi, I have a problem regarding a glass material: It looks exactly how I want in the engine’s viewport, but for some reason it looks smeared, pixelated and without any reflections in the renders.


The blue emissive material underneath doesn’t seem to be the issue, I did try to render without and the result was the same. Could this be some post processing issue? If so what should I deactivate so my render looks exactly like it does the viewport?

This is my glass material if it can be useful:

Thanks.
