Personally, I don't think this can be classified as a bug. It's just the way it works. In certain situations it can be very useful to determine where the object is, even if it's behind other objects. In other situations, it can be very confusing. The big problem is that Complete doesn't have a way to turn this off, as Infinite has. In Infinite, I turn off or on the red wireframe depending on what I want to see and so I don't have your problem.

I was now checking if this is announced in the comparison and indeed it is. See in the link, compare Complete with Infinite and see the point "Selected objects appear with a red wireframe", in the section "Real Time preview". Of course, it doesn't say "behind objects"... ;-)

That's why the PLE is good, to see this kind of things in practice. Did you try the PLE before making the purchase decision?
