Have you tried the "thin glass" option in the refraction settings?

Could you send us your scene (or a part of it where the issue can be seen)? https://corona-renderer.com/upload
We're interested in checking this. It looks like a known problem with light transport (https://coronarenderer.freshdesk.com/support/solutions/articles/5000516180) but kind of exaggerated.
Could be the directionality parameter in the light though.
