Problem description:

When enabling the mipmapBlur property in the Bloom effect from @react-three/postprocessing, certain objects in the scene disappear when viewed from specific camera angles. Disabling mipmapBlur causes the objects to remain visible, but introduces square artifacts on the MeshRefractionMaterial in those same camera angles.
