Dynamic Camera Map reflection "ghost"

[DoobesURU]

As @Hoikas figured this may be an engine issue (given it spans both OU and H'uru clients, that's likely accurate), I'm bringing this issue over here and closing the other.

When using DCMs, an avatar "ghost" seems to appear at random spots and views. Some have recently determined that it happens when a lamp or lamps are projecting a real-time shadow for the avatar. Either removing the Plasma RT Shadow of the lamp(s) in Korman or turning off shadows in-game causes the ghost to vanish.
