As a first guess, it looks a bit like z-fighting.
You are the boss here, so you are right ;) Just to pinpoint the "wall hack" issue... You need to be as close as possible to the door or wall. If you are only one step further, it is displayed correctly.
"PAUSED" is missing everywhere, not only by the wall or door.
I guess the demo could have the same issue - unfortunately not tested (yet) ;)
