What it does

The mod replaces Minecraft's default fullscreen behavior with a borderless windowed mode. The game keeps a regular window that covers the display, so switching to another program with alt-tab is quicker and the screen does not flicker during resolution changes. Because no exclusive mode is used, the window behaves much like fullscreen while remaining a window.

Borderless Windowed runs on Fabric and only on the client, so servers and other players need nothing extra. It is published for 12 release versions, with the latest file 1.0.0 for 1.21.11 dated 2026-01-18. The author notes that it works with most mods, and the mod is released under All rights reserved, so it is not open source.

Key features

  1. Borderless windowed fullscreen

    Minecraft runs in a window sized to the whole display, replacing the default exclusive fullscreen mode.

  2. Faster alt-tabbing

    Switching to another program or back to the game is quicker, which helps when the game runs alongside several monitors.

  3. Resolution switching without flicker

    Changing the resolution inside the game does not make the screen flicker, because the display mode is not reset.

  4. No exclusive mode

    The game behaves like fullscreen without taking exclusive control of the display, so other windows stay accessible.
