Resolved How to rotate UI in World space without flickering?

Hey,
I have a Problem with my Chat Box UI.
The Chat Box is in the World space and Should rotate to face the player's Cam.
But if I rotate the UI, then the Chat box Text and Icons start to flicker.

How can I get rid of the flickering?

I Use this in the Update to rotate the UI towords the Player Cam.

Code (CSharp):

1. private void Update() {
2.         this.transform.LookAt(transform.position + Camera.main.transform.rotation * Vector3.forward, Camera.main.transform.rotation * Vector3.up);
3.     }

 

Looks more like there's clipping problems, as if there's something in the same spot as your dialogue box, but there's not really enough information to go off of.

 

Hey,
Youre right. Thanks for the help and the quick reply.
I just deactivated every single element piece by piece to find the problem. There was another object, which caused the clipping.
