HDRP UI Panel seems to influence the lighting in the Editor scene view (Unity 6.0.0.0.17f1)

Hello! Can someone please help explain why adding a UI panel to a canvas in an empty scene causes the lighting to go weird in the Unity Editor?

Steps to reproduce:

  1. Create a new scene, leave the default camera and directional light as is.

  2. Create a new Game Object.

  3. Right click the Game Object and add UI > Canvas.

  4. Right click the Canvas and add UI > Panel.

  5. Click the Panel and set the image background color to black, full alpha (hex: 000000).

  6. Notice how the scene lighting looks incredibly over-exposed and bright:

  7. Disable the Game Object you created.

  8. Notice that the scene lighting goes back to normal.

I was of the impression that the default UI shader played no part in lighting.

Any ideas?

Thanks!

I think this is totally normal, as the UI in scene view is rendered as if it was a world canvas (else it would stick to the scene camera).
As such, it is rendered like if it was regular unlit 3D objects, and is taken in account for exposure, in scene view.
