Light artifact on the edges of a MeshInstance3D

Question

I created a very simple scene. Mesh Instance 3D nodes with a BoxMesh.
There’s a DirectionalLight3D on the scene.

In the inspector and also when I run the project from godot, I sometimes see these artifact on the edges of the boxes. It depends on the camera position and angle. It disappears when I move the camera, but it may happen on another edge when the camera is moved again.

What would be the reason?

Looks like the other NVidia driver issues, haven’t seen it in 3D yet

Graphical glitches - Issue #102219

Issue on the Godot GitHub: https://github.com/godotengine/godot/issues/102219 This issue has been confirmed many times already, and it’s a problem with the latest Nvidia 572.16+ drivers. A lot of Vulkan applications seem to be affected, and Nvidia is aware of the problem. There’s nothing we can do on the Godot side to mitigate this, so affected users can either: Roll back the driver to a previous version Wait for Nvidia to update their drivers with a fix Configure Godot to use Direct3D 12 in…

Thank you for that! I reverted the driver back to 566.36 and the issue is gone. So it looks like 3D is also effected.

I should continue with this driver until Nvidia has a fix.
Nvidia says it should be fixed in next driver, the one after 572.47
