Screen space refraction has a weird noisy ball on the center of it, with a kind of low quality pixelated look, only ways to get rid of it partially is by either increasing the IOR, increasing the Refraction Depth, or changing the roughness of the material to something that isn't between 0.01 - 0.3.
This applies to both the roughness and trasmission roughness
Side note : i tried changing all the settings in the render properties, nothing worked, speaking of which, Half Res Trace does NOT apply to Refraction, only Reflections.
Exact steps for others to reproduce the error
Just do a basic setup of SSRefractions, nothing more than that
More extreme example:
