Cubes Without Borders

by Kira-NT

Cubes Without Borders is a client-side mod that lets the game run in a borderless fullscreen window, so other applications on another monitor stay reachable.

FabricForgeNeoForgeQuiltClient-side onlyMIT LicenseOpen source1.16.5 – 26.2

What it does

The Video Settings tab gains a third choice, Borderless, next to the usual Fullscreen toggle. Selecting it fills the screen without a window frame, so other applications on a second monitor, or windows placed on top of the game, stay visible and the game is not minimized. A --borderless startup flag forces the same mode at launch regardless of the saved setting.

The default mode is minecraft:windowed, a low-latency borderless fullscreen. Players who see problems with it can choose windows:windowed, the true windowed fullscreen mode, in the mod's settings. Open source under the MIT License, the project is published for Fabric, Forge, NeoForge and Quilt, with files for 1.16.5 – 26.2. Cloth Config API, Mod Menu and YetAnotherConfigLib (YACL) are optional.

Key features

  1. Third fullscreen option

    Video Settings offers Borderless alongside the standard Fullscreen setting, so no separate menu is needed to turn it on.

  2. Startup flag

    The --borderless flag starts the game in borderless fullscreen whatever the saved settings say.

  3. Selectable display modes

    The default low-latency mode can be swapped for a true windowed fullscreen mode when hardware or drivers cause trouble.

  4. Optional config screens

    Cloth Config API, Mod Menu and YetAnotherConfigLib (YACL) can be installed to add a settings screen for the mod.

Questions

Does Cubes Without Borders need Fabric API to run on Fabric?

No required dependency is listed for Fabric, Forge, NeoForge and Quilt. Those three add config screens if they are installed.

Which fullscreen mode should a player on a desktop operating system choose?

The default minecraft:windowed mode is low-latency. If the cursor disappears in inventories or the mode misbehaves, windows:windowed is the alternative, and it can be set in the mod's settings.

Why does the Fullscreen setting show only a toggle in the Video Settings?

A rebranded fork of the video settings screen, or a version the mod does not yet support, can hide the Borderless option. The vanilla Video Settings can be reached from the custom screen with Ctrl + Shift + P.
