About this project
What does Cubes Without Borders add?
Cubes Without Borders
A mod that allows you to play Minecraft in a borderless fullscreen window. This means you can keep the game open while interacting with other applications on a different monitor, or even directly on top of Minecraft itself, without the game being minimized.
Unlike other "borderless fullscreen" mods, Cubes Without Borders is highly configurable, does not hinder your input latency, and explicitly supports all major platforms - Linux, macOS, and even Windows - instead of providing a passable experience for only one group of players while making it seem as though others do not exist.
Usage
To enable borderless fullscreen, go to the Video Settings tab, where you would typically find the Fullscreen setting, and switch it to the newly added third option: Borderless.
Depending on whether you have Sodium installed, you may find this option in one of the following locations:

Additionally, the mod introduces a --borderless startup flag that forces the game to launch in the borderless fullscreen mode, regardless of your current settings.
