ShaderGraph sprite is replaced by a blue box when using ShaderGraph Material

--

-

Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Assets/Scenes/2D Shader Studies.unity” Scene
3. Enter the Play Mode
4. Exit the Play Mode
5. Observe the view

Expected result: ShaderGraph sprite stays the same
Actual result: ShaderGraph sprite is replaced by a blue box

Reproducible with: 2023.1.0a11, 6000.0.13f1
Not reproducible with: 2022.3.40f1, 2023.1.0a10
Couldn't test with: 2021.3.40f1 (there is no ShaderGraph material)

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

Note: Sprite shows up again when reimporting the ShaderGraph material or opening ShaderGraph and saving it

  1. Resolution Note:

    By design, 2D SRP-Batcher does not support access of TexelSize property in Shader. The Custom Node in the project does that and uses SRP-Batcher to render the Sprite. To fix, either please disable SRP-Batcher for that shader or add a custom node to set TexelSize within graph.

    You can simply a Vector4 MainTex_TexelSize to the ShaderGraph which also automatically populates the required value and fix the issue.

  2. Resolution Note (fix version 6000.0.19f1):

    Fix case where ShaderGraph sprite is replaced by a blue box when using ShaderGraph Material
    Fix will be available on Unity 6000.0.19f1 and above

    While I may be biased (it's my bug report, after all), I think this question needs to be looked a little deeper.

    In 2022 LTS you can freely use SRP-Batcher with the _TexelSize property.

    Things Broke down somewhere around this fix: https://issuetracker.unity3d.com/issues/the-maintex-texelsize-property-is-not-being-set-when-compiling-a-shader

    I personally think the focus should be in re-enabling support for _TexelSize in SRP-Batcher materials/shader, and not simply removing SRP-Batcher compatibility with these materials.

    As in 2020, _TexelSize making a material SRP-Batcher incompatible was seem as a bug:
