- You should report it to NVidia. Godot has no control over driver problems. NVidia has to fix them. This happens every 6 months or so and they eventually resolve the problem.
- If you are on Windows and you started your project before 4.6 was released, your default rendering driver is Vulkan. Go into the project settings, and change the Windows Rendering Driver to D3D12. This may fix it.
- If not on Windows, you can try playing with your OS driver, or you can roll back your NVidia drivers until they fix the issue.
