Reproduction steps:
1. Open the attached “IN-110055.zip” project
2. Open the “SampleScene”
3. Enter Play mode
4. Observe the Game view

Expected result: The Render Target is correctly displayed on the RawImage
Actual result: The Render Target is not visible/displayed on the RawImage

Reproducible with: 2021.3.54f1, 2022.3.64f1, 6000.0.54f1, 6000.1.13f1, 6000.2.0b12, 6000.3.0a3

Reproducible on: Windows 11, Windows 10
Not reproducible on: No other environment tested

Notes:
- It appears that the wrong “Y” value is used when calling CopySubresourceRegion()
- Does not reproduce with OpenGL Graphics API
- The issue can be bypassed on DirectX by setting the Viewport value to (0,0.25,0.5,0.5) instead
- Also reproducible in the Player
