Material Refracting back on itself?
Hello, I understand similar questions have been asked before, but I cannot seem to find an answer to this issue (If it's an actual issue). The glass material in the image seems to refract back around the corners/through the material when refraction is enabled. It's using the typical setup for refraction (lerp between 1/IOR with a fresnel) so I'm unsure what I am doing incorrectly.
Although I'm using a scene capture cube to fake the reflections, using any of the different lighting modes seem to have the same issue.
Any help would be great.
Thanks, Bob :)

In Engine 4.15.2 I have same problem with Pixel Normal Offset enabled! The problem was in this option:
It was enabled first (my project had mobile version) and I got strange squeezed results at the middle and far distance from glass:
Of course it should look (and it does with option disabled) like this:
