Issue ID

UUM-11629

Regression

No

Modifications to Mesh.triangles are not uploaded to the GPU when the Game view and Scene view window are open at the same time

--

-

How to reproduce:
1. Open the attached project "ProceduralGeneration.zip"
2. Enter Play Mode

Expected results: Mesh is generated
Actual results: Mesh is not generated

Reproducible with: 2021.3.8f1, 2022.1.13f1, 2022.2.0b4, 2023.1.0a5
Could not test with: 2020.3.38f1 (compilation errors in the Console window)

Reproducible on: Windows 10

No repro: MacOS

Workaround:
* the mesh is correctly updated when scene view is not visible when entering playmode
** if Game View > Enter Play Mode is set to Maximized
** Or, if Scene View tab is hidden or closed
* OR - no repro when MeshFilter.mesh is not used in OnDrawGizmos (instead can use MeshFilter.sharedMesh)
