### Godot version

v4.0.3.stable.arch_linux

### System information

Arch linux  - OpenGL API 4.2 (Core Profile) Mesa 21.3.9 Amber - Compatibility - Using Device: Intel Open Source Technology Center - Mesa DRI Intel(R) HD Graphics 2500 (IVB GT1)

### Issue description

I wrote a simple colorize shader:
```
uniform sampler2D color_map;
void fragment()
{
	vec2 uv = COLOR.rg;
	COLOR.rgb = texture(color_map, uv).rgb;
}
```

But when I change the uniform parameter in the editor, it turned into this

However, this issue does not appear on Vulkan renderer (Foward+ and Mobile) 

### Steps to reproduce

Change value in the gradient in the shader parameter.
