The Artifact (Resurrection of Evil) when activated in the game is meant to slow everything down so you can pass or complete some task among other uses. I would say that part is normal. The problem is that the graphics are inverted upside down with a mirror image when you activate it.

edit: The Soul Cube is similar to the Artifact and what it is called in the original Doom 3.
