Does this happen to anyone else?

[Trollee]

Sometimes the floor randomly goes this color in Nuri's Madness. It is quite rare and completely random. I've so noticed it as well in Haunted Symphony and Boggy Waters the edges of the track become very contrasting in colours. I've found that minimizing the app and then going back into it usually fixes the problem. I'm just curious as to why this happens and if it happens to anybody else.
