Description

[EN] Fixes the black screen on the first launch after boot on NVIDIA Optimus laptops (e.g. driver branch 596.36). On a cold discrete GPU, the first swapchain configuration can fail and vanilla 26.2 never retries it, leaving a permanently black window while the game keeps running. This mod makes the engine retry swapchain reconfiguration every frame until the dGPU is ready, so the picture recovers automatically within seconds — no second launch needed.

[中文] 修复 NVIDIA 双显卡（Optimus）笔记本开机后首次启动 Minecraft 26.2 黑屏的问题（涉及 596.36 等驱动分支）。冷启动时首次启动需将独显从低功耗状态唤醒，首个交换链配置可能失败，而原版代码不会重试，导致窗口永久黑屏但游戏仍在运行（有声音、可操作）。本 mod 让引擎在窗口表面无效时每帧重试重建交换链，直到独显就绪，画面通常数秒内自动恢复，无需再次启动游戏。
