*Steps to reproduce:*
1. Create a new project with Cinematic Studio Sample or High Definition 3D Sample templates
2. Build And Run
3. Observe the Console

*Actual results:* "Shader warning in 'Hidden/HDRP/DownsampleDepth': implicit truncation of vector type at Packages/com.unity.render-pipelines.high-definition/Runtime/ShaderLibrary/DownsampleDepth.shader(81) (on metal)" warnings are thrown
*Expected results:* No errors or warnings are thrown

*Reproducible with versions:* 2022.3.491, 2022.3.51f1
*Not reproducible with versions:* 2021.3.45f1, 2022.3.48f1, 6000.0.23f1{*}{*}

*Tested on (OS):* macOS Sonoma 14.5 (Intel)
