### Godot version

4.1.1 stable

### System information

Windows 10

### Issue description

this is the default size loaded on startup 1024 which seems fine but it actually have loaded the default [2048] and ignored the size in project settings

changing it now to any size will break it

### Steps to reproduce

change 2d shadow atlas size in project settings while using compatibility renderer.
