NeoLoading-Vulkan-Fix

NeoLoading-Vulkan-Fix is a lightweight client-side mod that fixes crashes and freezes caused by NeoForge’s Early Loading Screen when Minecraft is running with the Vulkan graphics backend.

The Problem

When you switch Minecraft to use the Vulkan rendering backend (via GpuBackend), NeoForge’s Early Loading Screen conflicts with Vulkan’s window creation flow, causing the game to freeze or crash during startup.

How It Fixes It

This mod uses Mixin injection to address the issue at two key points:

1. Detects Vulkan — hooks into Window.createGlfwWindow to detect when Vulkan is the active backend
2. Skips the conflicting loading screen — when Vulkan is detected, skips EarlyLoadingScreenController initialization
3. Safely cleans up — in ClientModLoader.finish, uses GLFW native APIs to properly destroy the DisplayWindow instead of calling the original close() method

Compatibility

• Client-side only — no server installation required.
• No gameplay changes — purely a technical fix.
• Not needed if you are using Twilight Forest: Re26 — that mod already includes the same Vulkan fix. Please remove this mod to avoid conflicts.

If you’re using Vulkan with NeoForge and experiencing startup crashes, this mod should resolve the issue.
