Separate windows and drop-down menus cause display issues in the main editor window

[Lilith-In-Starlight]

Godot version

4.1

System information

Godot v4.1.stable - Windows 10.0.19045 - Vulkan (Compatibility) - AMD Radeon HD 8400 / R3 Series () - AMD A6-5200 APU with Radeon(TM) HD Graphics (4 Threads)

Issue description

When clicking on "create new project", the window to create a new project will display the contents of the project manager and not the main window. Interacting with the new project window will briefly make the project manager display the current stateof the new project window.

Drop-down menus have a similar issue. They display the engine's main editor window, but hovering on them will cause the main window to display the contents of the menu for a brief moment

Steps to reproduce

For the create new project window:

• Open godot
• Create new project

For the menus:

• Create a godot project using a Godot 4.0 alpha (this bug was probably introduced in the later alphas, when I stopped trying them out)
• Open that project in godot
• Use any of the editor's drop-down menu (Scene / Project / Debug / Edit / Help)

Minimal reproduction project

N/A. I don't even get to create a project before the issue shows up.
