Nice idea, now the window resizes quickly. However, the program now takes significantly more time to start. This shouldn't happen, right?
Furthermore, now that the screen is resized even before the boot splash is gone the splash "jumps" and moves to the side of the window, sometimes it gets clipped too.
Nevertheless, thanks for your help.
I'm sorry that the question wasn't clear enough. Here's what I really want to do:
Running Godot makes it open at the same position and size as the last session.
It starts as if you changed the window size through the Project Settings.
The window doesn't open at a default size and then resizes and moves, it actually opens with the intended size and position straight away without the need to be adjusted.
I would like this behavior to be implemented in my application, I don't strictly need it but I wonder if there's a way to do this without adjusting the window after running.
It would be beneficial to know how to do this as it makes the window run smoothly, avoids artifacts and ensures that the splash is positioned correctly.
