Regression
No
Shaders are always recompiled when the Editor is opened
Reproduction steps:
1. Open the attached “IN-77989“ project
2. Open the “Level_Bionic_Downfall“ scene and observe the Scene view
3. Notice that the shaders appear cyan for a brief moment
4. Close the Unity Editor
5. Open the project again
6. Observe the Scene view
Expected result: The shaders are immediately rendered
Actual result: Shaders appear cyan for a brief moment, signaling shader recompilation
Reproducible in: 6000.0.10f1
Could not test with: 2021.3.40f1, 2022.3.37f1 (Could not resolve package errors)
Reproducible on: Windows 10, Windows 11
Not reproducible on: No other environments tested
Note: Could not search for regression due to package errors when downgrading the project

Latest issues
- Silent crash when clicking in Scene View in a specific project
- The Player renders black on a Quest headset when MSAA, Post Processing, and Spacewarm depth submission are enabled
- Graphics Compositor breaks Unity rendering when the "Output Camera" is changed to a scene Camera and one Camera SubLayer is active
- The Editor freezes on RenderGraphViewer.Repaint when entering too many characters in search fields without character limits
- Adding a new SubLayer in Graphics Compositor renders BaseLayer darker and makes it flicker
Resolution Note (fix version 6000.1.0a1):
The editor startup shader variant warmup had a bug that prevented correct variants from being warmed in time, thus causing the one frame of cyan. However, the cyan rendering does not necessarily mean recompilation. This also happens atm when the variant is loaded from the cache.
