OnCollisionEnter false positive

Unity Engine

HI,
I’m using the following function:

void OnCollisionEnter(Collision collision)
     {
  Debug.log(collision.gameObject.name);
}

I have 2 simple cubes with collider and rigidbody, of which collision detection=continuous.
If I take the 2 cubes and let them fall side by side but without touching, the OnCollisionEnter function is called which logs the name of one of the two cubes, yet they have never touched.
How come?
What am I doing wrong?

How close are we talking about here?

for example runs a finger through it,
or I try to hit one cube with another, without making them touch, and the OnCollisionEnter event is triggered.

same situation here. I’m using Quest 2 and XR Interactable.
When the sphere passes by, the collider name of the OnCollisionEnter is logged behind,
but the two objects are far apart8983330--1236241--ezgif.com-optimize (2).gif

I can confirm the same false positive happened to me. Especially OnCollisionStay is called continuously for a collider that is far apart. I think this is a unity bug, and I failed to find this in known issues.
