Reproduction steps:
1. Open the attached “IN-111158.zip” project
2. Make sure DirectX11 is selected as the Graphics API in the Player settings
3. Go to File > Build Profiles
4. Switch the active Platform to Android
5. Open the “SampleScene”
6. From the Hierarchy, select the “model_Foliage_GrassBatch_A” GameObject
7. Observe its movement in the Scene view

Expected result: The base of the mesh is static
Actual result: The base of the mesh is also moving/is animated

Reproducible with: 6000.0.55f1, 6000.2.0f1, 6000.3.0a5
Couldn’t test with: 2023.1.0a1 (Project would not open with earlier versions)

Reproducible on: Windows 11 (Radeon RX 7700S), Windows 11 (RX 6800XT)
Not reproducible on: Windows 11 (NVIDIA RTX 3500)

Notes:
- Does not reproduce with NVIDIA GPU’s
- Does not reproduce if DirectX12 Graphics API is used for Windows
- The base of the mesh should be static because of the vertex alpha channel color being correctly read and sent to the shader
- Only reproduces if Android Platform is selected
