Steps to reproduce

• Switch to the OpenGL driver in the Project Settings.
  • Make sure to start the editor with single-window mode enabled afterwards. This can be done by enabling Single Window Mode in the Editor Settings before changing the driver, or by opening the project in the editor directly with the --single-window command line argument.
• Add a WorldEnvironment node, a Camera3D node and a MeshInstance3D in front of the camera.
