Resolution Note:
The FrameDebugger inspects in realtime what is being submitted to render.
They have a custom VolumetricFog class with a method called UpdateNoise.
There, the user is not always performing the same Graphics API calls, this is good as an optimization, but they need to check if the FrameDebugger is enabled:
if (activeProfile.noiseFinalMultiplier != 0 && !activeProfile.constantDensity
#if UNITY_EDITOR || DEVELOPMENT_BUILD
|| FrameDebugger.enabled
#endif
)
This will always perform the Graphics.Blit that was making the FrameDebugger flicker, if the FrameDebugger is enabled.
The FrameDebugger stops the game logic, but the rendering logic can be different on everyframe, this is a limitation of the tool. To get an snapshot you can use other tools such a RenderDoc.
