World-Based Experience Is Unstable / the Objects Float or Change Size
The stability of AR in the Real World and SLAM type experiences may vary depending on the surface you're pointing your camera over during the initialization.
Carpeted, wooden or matte tile flooring, urban pavements and natural landscapes with trees and grass tend to have more distinctive features.
Reflective surfaces, such as glossy tile flooring decrease the stability of the surface recognition technology. The same goes for the plane monotone surfaces without any distinctive features.
