I have the same case and had the same problem, but it had nothing to do with the case itself.
I tried to leave on the protective film on the back that the phone came with until I received the skin I ordered, but it was ruining my pictures and looked exactly like what you have there. So I cut the corner of the film with an X-acto knife and it fixed the problem.
Sure you didn't just forget the film was still on there?
