Minecraft Borderless Window

⚠️ Important Notes

• The first version for Minecraft 1.21.11. Download the file for 1.21.11 and your loader; the 1.21.1 jars do not work here
• Minecraft 1.21.11 has its own "Inactivity FPS Limit" (in Video Settings, or on Sodium's Performance page): 10 FPS while minimized and, in its default "AFK" mode, 30 FPS after a minute without input and 10 after ten. It stacks with the mod's background options and the lowest limit wins. To use only the mod's Idle FPS Limit, set Minecraft's to "Minimized". Pause Rendering When Minimized still goes further than Minecraft: it stops drawing frames instead of drawing them at 10 FPS
• The fog toggles are independent. Minecraft 1.21.11 draws two fogs at once: the one from where you are (water, lava, the Nether, rain) and the one that hides the edge of the loaded terrain. Water Fog off clears the water and keeps that edge hidden; Terrain Fog off clears it everywhere
• Same config file and option IDs as on 1.21.1: copying config/borderlesswindow.json from a 1.21.1 instance carries your settings over

✨ New Features

• Everything from 1.10.0, on Minecraft 1.21.11: the three screen modes and configurable F11, the FPS counter, the background options, the fog toggles and Fog Start, cloud height, sky and weather, the held item name, screen and camera overlays, split FOV, distortion and view bobbing, zoom, enchantment numerals, draw distances, and Minecraft's own sliders that Sodium leaves out
• With Sodium, the mod's six pages and the Screen Mode selector work as on 1.21.1. Iris shaders work too: the rain is hidden, and packs that draw their own sky keep their sun, moon and stars

🔧 Technical Changes

• Ported to Minecraft 1.21.11, whose rendering changed throughout since 1.21.1. Every hook was checked against the 1.21.11 code on both loaders:
  • Fog: one mixin for both loaders, on the fog data FogRenderer.setupFog builds before uploading it. NeoForge's RenderFog event and the Fabric-only fog mixin are gone. Sodium reads the same data, so the toggles work the same with it
  • Clouds: the cloud height is now an environment attribute; the mod moves only the drawing, in CloudRenderer. Dimensions without clouds never reach it
  • Sky and weather: the sun, moon and stars in SkyRenderer, the rain and snow in WeatherEffectRenderer
  • Particles: ClientLevel.doAddParticle, where Minecraft applies its own 32-block limit
  • Frame rate caps: FramerateLimitTracker, where Minecraft's own Inactivity FPS Limit lives
  • Unfocused volume: scales each sound's volume as it reaches OpenAL (Channel.setVolume). Minecraft 1.21.11 no longer has a listener gain
• Distortion: Minecraft now tracks the portal and Nausea apart. Inside a Nether portal the Portal slider still rules the whole spin, Nausea included, as on 1.21.1 — also when arriving inside the destination portal
• The zoom key's Controls category is now registered by each loader, as Minecraft 1.21.11 requires
• On Fabric, the bundled resource loader is now fabric-resource-loader-v1. Fabric API is still not required

📦 Dependencies

• Minecraft 1.21.11 with NeoForge 21.11.x, or with Fabric Loader 0.17.3 or newer
• Optional: Sodium 0.8.x on either loader, and Mod Menu on Fabric
