Fullscreen+

🐛 Fixes

Startup Input Bug

• fixed a bug where mouse input felt broken on first launch (weird hovering, unresponsive clicks)
• the mod was cancelling vanilla's window init before Minecraft had a chance to set up its internal state
• now lets vanilla handle the initial window setup, only takes over on actual fullscreen transitions

🎉 What's New

Dual-Monitor Support

• fullscreen now uses whichever monitor your window is on instead of always defaulting to primary
• auto-detects the correct monitor based on window overlap
• added a "Preferred Monitor" slider in settings to lock fullscreen to a specific display (0 = auto)

Unfocused FPS Limiter

• automatically caps FPS to 15 when the game window loses focus
• saves GPU and CPU while you're alt-tabbed
• configurable cap (1–60 FPS) and can be toggled off in settings
• enabled by default

Mode Cycling Keybind

• press F10 to cycle through Borderless → Exclusive Borderless → Native
• rebindable in Minecraft's controls menu under the Fullscreen+ category
• disabled by default, enable "Cycle Modes Keybind" in settings to use it

Cursor Confinement

• locks the cursor to the game window when in borderless fullscreen
• prevents the cursor from escaping to other monitors during gameplay
• disabled by default, toggle it on in settings

--borderless Startup Flag

• add -Dfullscreenplus.borderless to your JVM arguments to force borderless mode on launch
• useful for modpack developers and server launchers

⚙️ Technical

• new mixin targeting InactivityFpsLimiter for FPS throttling when unfocused
• keybind registered via Fabric Key Binding API with proper KeyBinding.Category
• cursor confinement uses GLFW_CURSOR_CAPTURED on fullscreen enter, releases on exit
• monitor detection uses GLFW overlap-area algorithm across all connected displays
• updateWindowRegion no longer cancelled when there's no state transition
