Chapter 23 starts at 1:08:32 with Mace cooking a macrobiotic dinner in the kitchen. The first several shots of him cooking show that the floor is spotless. At 1:09:20 Andy enters the scene, this is a headshot of Mace with Andy standing behind him over his shoulder.
She says "You cooked? Tempe? Oh, it's burning!" And at 1:09:23, just after she says "it's burning" the camera cuts to a full body shot of them both and you can see 3 red tapelines on the floor used to cue the actors on where they are supposed to stand in the shot (and previous shots).
The scene continues and at 1:09:49 the markings are gone again.
