Thanks for taking a look at this. It may also be related to Fogbugz issue 1152243, which affects Ambient Occlusion effect when "Multi-scale volumetric obscurance" is enabled.

The issue looks a little different- it might not be rendered twice for each eye, it might just have some sort of strange offset. So if it's a different issue, I would understand.

Thanks again!
