*Steps to reproduce:*
1. Create a new project with Runner Game template
2. Build And Run
3. Observe the Console

*Actual results:* "Shader warning in 'Hidden/Universal Render Pipeline/StencilDeferred': implicit truncation of vector type" warnings are thrown
*Expected results:* No errors or warnings are thrown

*Reproducible with versions:* 2021.3.46f1
*Can't test with versions:* 2022.3.52f1, 6000.0.27f1, 6000.1.0a4 (No Runner Game template){*}{*}

*Tested on (OS):* macOS Sonoma 14.6 (M1), macOS Sequoia 15 (Intel)

*Note:*
