Custom shader is displayed incorrectly in the Play Mode when SRP Batcher is enabled

--

-

Reproduction steps:
1. Open the attached “repro_IN-71109“ project
2. Open the “SampleScene“
3. Select the “/Assets/Settings/URP-Balanced.asset“ and, under the “Rendering”, enable the “SRP Batcher“
4. Enter the Play Mode
5. Observe the Game view

Expected result: Half of the “Sphere“ GameObjects change their visual appearance
Actual result: All of the Sphere“ GameObjects change their visual appearance

Reproduced with: 2021.3.36f1, 2022.3.22f1, 2023.2.15f1, 6000.0.0b12

Reproducible on: Windows 10 (22H2)
Not reproducible on: No other environments tested

Notes:

* Reproducible in Player
* Making the Timer shader variable declaration be per material fixes the issue
* If you’re not able to see the “SRP Batcher“ parameter, make sure that the “Visibility“ is set to “All Visible“ in the “Edit → Preferences → Core Render Pipeline“

  1. Resolution Note:

    The custom shader is using a shader var "_Timer" that could be different per sphere (and each sphere is using its own material). This property "Timer" could have one different value per sphere. In ShaderGraph, the scope of this "Timer" var should be "Per Material" instead of "Global"
