Regression

No

Editor crashes when calling ComputeShader.Dispatch() with too many threads

Graphics - General

-

How to reproduce:
1. Open the attached project named "Case_1206509"
2. Open the Gameplay Scene located in the Scenes folder
3. Enter Play mode

Expected behavior: Editor functions properly or throws an error due to a high number of threads used
Actual behavior: Editor crashes

Reproducible with: 2018.4.15f1, 2019.2.18f1, 2019.3.0f5, 2020.1.0a19
Could not test with: 2017.4.36f1(Scripts breaking after downgrading)

  1. Resolution Note:

    There is no way to a priori know that the amount of work in a compute shader dispatch is too much for the GPU causing a driver timeout. In the future if we get device lost recovery and improved debug info from driver we might have more informative error.
