Cubes Without Borders Mod lets you play Minecraft in a borderless fullscreen window. This allows you to have the game open on one monitor and use other apps on a different monitor without Minecraft minimizing.

Features:
- Play in a borderless fullscreen window that doesn’t minimize when you click away.
- Works on Windows, macOS, and Linux for a consistent experience.
- Adds a new “Borderless” option to the existing “Fullscreen” setting in Video Settings.
- Does not add extra input latency, keeping your gameplay responsive.
- Includes a startup flag to force the game to launch in borderless mode.
- Offers several different fullscreen types in its configuration for advanced users.
Configuration:
This mod adds a startup flag, --borderless, which forces the game to launch in borderless fullscreen mode. For more options, you can edit the cwb.json file directly. If you have YACL or Cloth Config installed, a settings screen will also be available in the game.
How to Use:
- Go to the Video Settings menu in the game.
- Find the Fullscreen setting.
- Change the option to the new Borderless setting.
- Click Apply or Done to save your changes.
- You can also press F11 to switch directly into borderless mode, as it becomes the new default for fullscreen.
