Global uniform does not exist error on project startup

[EspeuteClement]

Tested versions

v4.3.dev6.official [89850d5]

System information

Godot v4.3.dev6 - Windows 10.0.19045 - Vulkan (Mobile) - dedicated NVIDIA GeForce GTX 1660 Ti (NVIDIA; 31.0.15.3699) - AMD Ryzen 5 2600 Six-Core Processor (12 Threads)

Issue description

When opening a project that uses a global uniform of type sampler 2d, an error is shown in the godot console output Global uniform 'noise' does not exist. Create it in Project Settings. while the uniform actually exist in the project.

This was also reported in a new comment on a closed issue here : #57200 (comment)

Steps to reproduce

1. Create a project using the Mobile render target, create a new global uniform named noise of type sampler 2d, set it to a noise texture
2. Create the following shader

shader_type canvas_item;

global uniform sampler2D noise;

void fragment() {
	COLOR = texture(noise, UV);
}

3. Assing the shader to a sprite2d node, save the scene, reload the editor
4. Observe the error messages in the ouput console

I did the test and i can confirm the error happens, also this a regression caused by #60965 in v4.3.dev1

A thing i noticied while i did my test is another bug: When i create a resource directly in the project settings option, the resource is never saved inside the project file, using notepad++ i see the file changed but when i reload nothing changes and the resource is not stored. Now if i use a resource already saved in a separated file, the project file updates correctly. Revert #60965 doesn't solve this part.

I tested compiling from master daa81bb and this error was already solved by #91414

The resources not being saved in the global shaders problem persists, should a separated issue be opened for that?

Thanks, closing as fixed by #91414.

Yes, that sounds relevant. Could you open one if you have a reproduction project?
