Borderless Mining Revived: Borderless Fullscreen for Minecraft (Fabric 26.3)

Alt-tab without the black screen. Borderless Mining makes fullscreen use a borderless window, so you can use a second monitor, Discord, OBS or a browser without Minecraft minimizing or flickering.

✅ Updated for Minecraft 26.3 on Fabric, rebuilt for the new SDL3 window system.

🖥️ Features

• Instant alt-tab: no minimizing, no black flash, no resolution switching
• Multi-monitor friendly: pick which monitor fullscreen goes on
• Custom window size & position: span monitors, leave room for a taskbar, or make an ultra-wide setup
• Works with vanilla's 26.3 fullscreen options: set Exclusive Fullscreen to OFF and Borderless Mining applies your monitor and size settings. Set it to ON for true exclusive fullscreen
• Config screen through Mod Menu, with an optional macOS toggle

💡 Great for

Streamers and content creators, people with two or more monitors, and anyone who alt-tabs to wikis, guides or Discord.

📦 Requirements

Fabric Loader + Fabric API, client only. Mod Menu is optional (config screen).
