### Godot version

4.0

### System information

Windows 11

### Issue description

So on my monitor with 2560x1440 resolution retrieved by the `DisplayServer.get_window_size` method shows 2562x1442, which I think is incorrect. A similar result returned by `get_viewport().size`. But it's become correct if the `Resizable` property is turned on.

### Steps to reproduce

Create the project, add a label to observe the resolution text, set the full-screen mode in the project settings, toggle off the `Resizable` property, and run the project.
