Refraction and Pixelation?

[l1tay2]

I am attempting to create a snow globe and have noticed that some of the objects inside the "glass" are pixelated. I am guessing that the glass globe is causing this due to refraction.

Any ideas as to why refraction would pixelate an object or how to solve? I am using progressive rendering and everything else is fine. When i remove the globe, the pixelation goes away.

Thanks.
