HDRP Cluster artifacts when having more than 100 lights
Steps to reproduce:
- Download this project: [https://drive.google.com/file/d/1P1hNzK_9Pw8_E-GKs1liGAH9LWd-cdUn/view?usp=sharing]
- Open it with latest Unity on Windows or Mac
- Set the resolution to 4K
- Make sure you have all the Point Lights enabled in your scene
- Notice Clusters are flickering all over the GameView (c.f the gif below)
The bug has been there for a long time. Disabling many Point Lights makes it disappear, the same if you switch to a lower resolution. It seems related to the lightlistbuild-clustered.compute.
