When Godot starts the game, it first goes fullscreen and then shrinks. How can I remove the fullscreen phase and directly enter the pre-set screen size? thanks！！
Hi,
Check the value of Project > Project Settings > Display > Window > Mode. You can play around with this value and the other ones. You can also change the Window Width/Height Override values to launch the game at a given window size, regardless of the viewport size.
I hope that will help. If not, feel free to share more context about your project setup, some code that may change the screen on start, etc.
