Hi Justin, I've experienced the same problem with the two new overlay modes. I'm not sure what is wrong, but even the examples don't work correctly for me. The only one that is consistent and works correctly is OBJECT_DEPENDENT_WITH_ORTHOGRAPHICS_OVERLAY.
Hopefully these issues will be resolved at some point as these are really great features.
