This is a shot of the sim just as the lines appear again, you should be able to see on the altimeter the height that these lines appear again after dissapearing.
That's entirely different situation than the one you initially described. Your altimeter shows 1630 ft, and Zurich ground is 1416 ft so, lines are disappearing at 214 feet NOT 15!!
And that's how the scenery has been made: you surely don't need taxiway lines when flying, so the fps is kept up in the most critical phase of the flight, the final approach.
