[WebGL] Blit with Custom Shader is not rendered in Player

--

-

Reproduction steps:
1. Open the attached “WebGL_URP_CustomShaderBugDemo.zip“ project
2. Change platform to WebGL
3. Build And Run the project
4. Observe the Player window

Expected result: All images are rendered
Actual result: Images under “Blit with custom shader“ are not rendered

Reproducible with: 12.1.11 (2021.3.26f1), 14.0.7 (2022.3.0f1), 15.0.5 (2023.1.0b19)
Could not test with: 16.0.1 (2023.2.0a17) (Errors in the Console)

Reproduced on: Windows 10
Not reproduced on: macOS Ventura 13.3.1 (Intel)

Notes:
- Could not test with HDRP (Broken Shaders)
- Not reproducible with Standalone Player

  1. Resolution Note:

    By design: Custom shader used for blit does not specify ZTest Always, therefore is uses ZTest Lequal. The render texture is not cleared before blit, so the depth buffer values are undefined, and the blit simply fails ztest depending on the render texture contents.
