URP 2D Lights jitter on movement (Mobile)

Hello all.

I’m using the URP 2D Lights.

I have in my game two analog sticks, one to control the rectangle movement (using rigidbody2d velocity, gravityScale is at 0) and another one to control the direction of the light. The lights are child of the rectangle and they don’t have any kind of rigidbody on them, they are just point lights.

My problem is that whenever i’m moving my rectangle, the lights begin to jitter.

This problem only occurs when I build the game and run on my mobile phone, it is a Samsung Note 8, tried with different phones with no luck.

In the gifs below I show the difference between running inside the editor and the build version running on mobile.

The rectangle was falling at a constant speed with rb.velocity at -1 in the Y axis. Using the left analog stick I alter the velocity on the rectangle rigidbody2d to make it move sideways, up and to boost the down speed (I didn’t use it during the recording).

I don’t have any kind of fps drops or performance issues on the phone but the “deeper” I go, the jitter intensifies, alot.

Tried to change from moving the rectangle using Rigidbody2D to Translate instead and also using differente types of updates with no luck also.

Can’t lights be within a moving gameobject?

I’m using Unity 2020.3.15

Another example:

I have a square moving right at a constant velocity of (4,0) and a point light as a child of this square. The distance is a Vector2.Distance between them.

It’s running on android mobile, in the editor, this jittering does not occur. Tried to set the Application.setFrameRate to differente values with no luck also.

Even if it is not a child, even if I put the movement script directly on a light it still has this weird behaviour on mobile.
Update:

Tried to remove all movements from the square and put them on the black screen background, now the only thing that moves is the background. The light still has this weird behaviour. The background is a complete separate gameobject with no children.

The only case in which the light does not jitter is when I disable all movements from everything.
