Is there a far clipping distance for UI elements?

I have some UI elements in my game. The Canvas is Screen Space Overlay. I'm using Unity 2018 LTS, last version.
The UI elements are not rendered-visible when far from Camera (about 1000) but my camera far clipping plane is set to 5000. The UI elements have not any layer assigned, so it is not a cull distance issue.
I want the UI elements to be rendered and visible at any possible distance (camera far clipping plane).

Any idea?

 

If the canvas is really set to "screen space - overlay" everything inside should be rendered for sure. No camera is used for that mode, so it cannot be related to clipping distances.

 

This is probably dead, but a work around that i found was to have the UI element move closer to the camera. (worldPointTransform = Transform component of the worldPoint) (If you only have a position, you will need to create a new Gameobject in game to make a Transform) =>

Transform worldPointTransform;

void Start()
{
worldPointTransform = new GameObject().transform;
}

Code (CSharp):

1. worldPointTransform.LookAt(Camera.main.transform); //looks towards the camera, so the transform.forward is pointing towards the cam
2.  
3. worldPointTransform.position += worldPointTransform.forward * distanceDivider; //example, if distanceDivider = 2, the worldPoint is set to the halfway point from the camera to where it originally was
