### Godot version

4.0.stable.mono

### System information

Windows 10, NVIDIA RTX 2060 (Driver 30.0.14.7284), Vulkan 1.2.175 Forward+ (Editor)

### Issue description

When changing certain Global Shader Parameters (in this case, a mat4) in the Project Settings, the value sent to the editor 3D view appears to be undefined, resulting in garbage values sent to the shaders.

As an example here, I'm using a mat4 to describe global light directions for a lighting shader
Note that the shader receives a different value even when the editor is being set to the same values

Setting the global parameter from a script does pass the correct value to the shaders

I have also determined the shaders in the editor also do not get correct values from the `project.godot` when loading the project.

### Steps to reproduce

- Create a Global Shader Parameter of mat4 type (Project > Project Settings... > Shader Globals)
- Create a shader that visualizes the value of the mat4 (`global uniform mat4 global_mat`)
- Attempt to modify the global in the same Project Settings menu, the shader will receive garbage values
