Dark Specks With Omni Light In Scene

Godot Version

v4.2.1.stable.official [b09f793f5]

Question

Black specks appear in my scene when an omni light is present. The specks flicker and move when the editor camera moves. They appear both in-editor and in-game. This issue occurs only on my desktop and not my less-powerful laptop. I am able to reproduce the issue in a scene with just a MeshInstance3D plane and a default omni light. The default environment and directional light are disabled.

Additional details from further testing:

  • One other user has reported this issue with no solution. They have the same graphics card I do (AMD Radeon RX 7800 XT). Black artifacts on 3D Mesh
  • The issue only occurs on the Forward+ renderer, and not on the Mobile one
  • The issue occurs even in a new project with default settings containing only a minimum scene to reproduce (one MeshInstance3D plane and one OmniLight)
  • The issue persists in the most recent Godot 4.3 dev snapshot
