Borderless Mining

Borderless Mining changes the fullscreen option to use a borderless window that fills the screen. This allows you to have Minecraft open on one monitor, while using other programs on another monitor - as normally Minecraft minimises when you unfocus it. This mod also adds the Borderless Windowed option to the Video Settings screen, so you can easily disable the mod ingame, and has a configuration menu accessible through Mod Menu.

Works on vanilla servers, and modded servers without the mod installed!

This mod is a rewrite of a Forge 1.12 mod, Fullscreen Windowed (Borderless), however it used to be a fork of that mod (which the 1.12 version of this mod is) - see the bottom of this page for the original description.

See Borderless Window by nekeras if you're looking for a similar mod for Forge 1.14+

On macOS this mod is disabled by default, as it is impossible to position the window above the menu bar, and macOS has better fullscreen support anyway.

Old 1.12.2 mod description:

This is the latest released version (1.6.0) of the mod Fullscreen Windowed (Borderless) by hancin for MC 1.12-1.12.2, plus a fix for window resizing by me, compiled by Brycey92. This fork will be obsolete if this PR is merged.

This fixes the bug where the window is not resizable after exiting fullscreen. This is a bug in LWJGL, and is fixed by Fullscreen Fix and in current versions of Forge. However, the existing fixes are not applied to Fullscreen Windowed (Borderless), so this fork fixes it in that mod.

See the original Github post by Brycey92 here.
