Glow light bugs (bright spots) flickers on surfaces when moving camera?

Godot Version

4.5, but more intensive in 4.6

Question

Does anyone knows why I these horrible light spots shows up all over the place when moving the camera? And any proper way to prevent it?

From what I found out:

  • This seems to be related to the glow as it only happens when it is enabled.
  • Tonemapping doesn’t help either.
    It still happens even with no lights (only environment)
  • When glow is enabled, it seems any walls will give this weird effect.

The strangest thing is, is that it only happens when the arms mesh is visible. Which has a metallic value of 0.7.

The wall material doesn’t seem to matter. It happens when specular is at 0 and at 1. Or roughness at 0 or 1.

So… high metallic materials bugs the lights if glow is enabled?
