Tested versions

Tested in 4.3.stable

System information

Arch Linux with Hyprland

Issue description

I am using a Framework 13 laptop that is set to scale the laptop display to 2x. My monitor is set to scale to 1x. When the Godot Editor is set to "Auto" scale, it only uses 200%, even on the 1x monitor.

Steps to reproduce

1. Using Wayland, set one monitor to 1x scale, and another to 2x scale.
2. Set Godot to prefer Wayland (run/platforms/linuxbsd/prefer_wayland in editor settings)
3. Set Godot's display scale to Auto (interface/editor/display_scale in editor settings)
4. Restart Godot
5. On both monitors, Godot scales to 200%.
