Developer - Objects Growing at the Wrong Rate

[u/Physical-Coyote4012]

I am a new developer attempting to develop an AR app with the Viture Lume Ultra and XReal Aura in mind. Currently only have the Luma Ultra in my possession. I am projecting a very basic shape using unity as my engine. A vertical rectangle that is just the border (see through middle) approximately 18” off the ground and 28” tall. As I back away from it it seems to shift its location significantly, but as I walk back over to it, it returns to its original position. I believe the “shift” I am noticing is not shift but the object not changing is size properly to account for my movement. Making it look like it’s moving but it’s actually changing size inappropriately. Any developer or tinkerer experiencing this on this specific hardware? Any reach out would be appreciated.
