Behavior/info on the world loading screen from before 1.19.3 (mod version 1.1.1 and older)
Since 1.18.2, the client only quits the world loading screen once the chunk it is in has been received... and at least 2 seconds have passed. By default, the mod fixes that behavior. Additionally, you can also fully get rid of the screen.
If you want to fully kill the screen, you can toggle a config option (you need modmenu and Cloth Config API for that). Keep in mind this reintroduces a client bug where you can briefly (only visually) fall through the world if your network connection is slow or the server is loading chunks very slowly after a world change.
Here are some video comparisons of Vanilla vs. the mod with the instant-close option enabled:
Credits to the well-thought-out name and wonderful icon go to mdcfe.
You can download the mod from Modrinth or the GH downloads page.
