How to reproduce:
1. Create a new Unity URP project
2. Import the attached "Example" image
3. In the Inspector, set the Texture Type to Sprite (2D and UI)
4. Make sure that the Sprite Mode is set to Single
5. In the Hierarchy, create a Canvas UI GameObject
6. Create a nested UI Image GameObject called "Background"
7. In the Inspector, set the "Background" GameObjects Height to 2000 and Width to 3000 in the Rect Transform component
8. In the Image component, change the Color to black
9. In the Hierarchy, create another UI Image GameObject
10. In the Inspector, set the "Image" GameObjects Height and Width to 500 in the Rect Transform component
