--

-

Steps to reproduce:
1. Open the attached user's project "ShaderWarmup2022.zip"
2. Switch to Android and build
3. Once application launches, press the "Warmup All Shaders" button
4. Observe the time it takes to warmup the shaders

Expected results: Shader.WarmupAllShaders time is similar to 2021.3
Actual results: Shader.WarmupAllShaders takes from 0.8s to 1.5s longer on 2022.3.10f1 and higher

Reproducible with: 2022.3.10f1, 2022.3.45f1, 6000.0.18f1

Testing Environment: Windows 11
Not reproducible on: no other environment tested

Notes:
-Issue reproduces on iOS according to the customer
-Issue reproduces with OpenGLES and Vulkan Graphics APIs
-With the affected devices, the Shader.WarmupAllShaders takes around 0.8s - 1.5s on 2022.3.10f1, while on 2022.3.9f1 it takes around 0.1s - 0.2s

  1. Resolution Note:

    This is caused by a fix to another issue. Before the fix it would warm up only the first variant per shader pass and skip the rest.
