What version of VfS you are using? Do you have emissive material? Are you using real glass( with refraction layer) or faking glass (only a reflection layer with transparency)?

If you have small object with emissive material with a very high intensity, you could get these splotchiness. Make a test by reducing or disable the emissive material to see if you still getting the stain. You should use emissive material to give the illusion that you have a light source, but use a rectangular o omni lights to produce the illumination. Best
