Description
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 non-exclusive fullscreen, go to the Video Settings tab, where you would typically find the Fullscreen setting, and switch it to one of the newly added options: Borderless or Windowed - whichever works best for you.
Depending on whether you have Sodium installed, you may find these options in one of the following locations:
Additionally, the mod introduces two new startup flags, --borderless and --windowed, which force the game to launch in borderless or windowed fullscreen mode, respectively, regardless of your current settings.
