Steps to reproduce:

1. Create a new project from an High Definition 3D template.
2. Create a cube in Hierarchy and then pull it into the Project window to create a prefab.
3. Open the prefab.

Actual results: Continuous ghosting of all UI elements in scene, windows behind the editor can show through as well if you bring up the context menu.

Expected results: No issues entering the prefab scene.

Reproducible with versions: 6000.0.0f1, 2023.2.20f1, 2023.2.0a22

Not reproducible with versions: 2023.2.0a21, 2022.3.26f1, 2021.3.37f1

Tested on (OS): Ubuntu 20.04, MacOS

Notes:

• There is a large amount of info in the comments of port UUM-71355: please refer to this.

* The problematic option seems to be {}Rendering -> Color Buffer Format{}. High Fidelity (which is the default quality level for the template) uses R16B16G16A16 while the other two use {}R11G11B10{*}. Toggling this option or changing the quality level will showcase the issue.
* It could not be reproduced on Nvidia 1650Ti, but could be reproduced with RTX 2080 Super (Max-Q)(nvidia driver 535) and RTX 3090 (nvidia driver 545) and RTX 4090 (driver unknown). It is perhaps associated with RTX enabled cards.
In some earlier 2023.2 versions that repro this, the issue also occurs in scene view. There is no problem noted in the Game View.

• Attached two .mp4s of this issue occuring in different projects.
• Issue did not reproduce on Mac.
• This did not occur with URP, tested with both OpenGL4.5 and Vulkan.
