### Minimal reproduction project (MRP)

Start with the attached project.zip and reproduce the texture jitter by moving the camera above the black border while looking at it, using the listed Godot 4.2.1, Windows, Vulkan, and Radeon setup as reference. Compare editor and play mode behavior; done means identifying the rendering cause and confirming that camera movement no longer produces the reported jitter.
