About this project
What does WindowedFullscreen add?
Borderless Fullscreen
Finally, true borderless fullscreen for Minecraft!
Are you tired of the long loading times when switching between fullscreen and windowed mode? Or do you use multiple monitors and want to switch seamlessly between Minecraft and your browser or Discord without the game minimizing?
Borderless Fullscreen Switcher is the solution. This mod removes the window border and ensures Minecraft fills your entire display, while technically remaining in windowed mode. It’s the best of both worlds: the clean look of fullscreen with the flexibility of a window.
🔥 Features
Spoiler
Seamless Multitasking: Tab out of the game without the window re-rendering or minimizing.
No Annoying Borders: Runs in a clean, borderless window.
Performance-Friendly: No unnecessary menus or complex configurations – just install and play.
Lightweight: Built on modern Fabric standards for maximum compatibility.
🚀 Why this mod?
Many existing borderless mods are outdated or overly complicated. We use a direct approach via the GLFW interface, making the mod extremely stable and ensuring it works perfectly on newer Minecraft versions
