Resolved Elements float on screen when using RuntimePanelUtils.CameraTransformWorldToPanel

I'm rendering some VisualElements that are positioned in world space, above game objects.
Here is a method that is called in each Update.

Code (CSharp):

1.     private void UpdatePosition(VisualElement item, Vector3 anchor) {
2.       var root = _underlay.Root;
3.       if (item.panel != null) {
4.         var position = RuntimePanelUtils.CameraTransformWorldToPanel(root.panel, anchor, Camera.main);
5.         item.transform.position = new Vector2(position.x - root.layout.width / 2,
6.                                               position.y - root.layout.height / 2);
7.       }
8.     }

Item is the small VisualElement I try to position.
Anchor is world space position, where it should be placed. It doesn't change over calls.
_underlay is a wrapper for an invisible uxml, that is stretch over whole screen.

Everything is working well except when I move the camera - then items floats around the anchor point. It stops at anchor whenever I stop moving camera.

Her is a gif of this behavior. In game it is much bigger - due to faster camera movement. Notice the element with yellow question mark strangely floating when camera is moved. When camera stops, it snaps in place.



Am I doing it wrong? Or is it due to differences in UI and Update update times?
Is there a better way to do it?

 

That was it, indeed! Thanks!
