These reflections are from the new Dynamic Indoor Environment Map beta. Just to be 100% sure, I’ve turned the beta feature off and did not see any of these reflections.
Also, looking at your test place shows that you’ve got signs up that make it seem like Glass making objects appear invisible is a bug - it’s actually been known since it was added:
Warning: Non-opaque Objects - Non-opaque objects are currently not visible through glass. This includes, but is not limited to, transparent parts, decals on transparent parts, particles, and world-space gui objects. This behavior matches the refraction on high quality smooth terrain water. This was implemented so refraction wouldn’t have a large performance impact. This behavior may change. We do not recommend relying on this behavior for gameplay.
I do see some odd Z-indexing behavior in your test place, but I fail to see a relation. I also see some odd behavior in which DepthOfField causes some things to appear lighter and darker as you move towards them in your test place.
ForceFields at 0 transparency aren’t opaque - they always appear slightly transparent unless a negative transparency value is passed.
Beta on:
Beta off:
There obviously are some lighting bugs that are apparent in your test place, but I believe some of these are not related to DepthOfField.
