 - `0003-vdi-input-priority.patch` 在 Qt 根目录应用。可选地让帧就绪后的连续输入先执行，最多 32 条或 2ms，不能跨窗口/焦点/其他事件。`VDI_INPUT_PRIORITY=1` 才启用，默认关闭。另提供 `VDI_INPUT_TIMING=1` 的汇总统计，区分 SDL 输入派发年龄与主线程呈现调用耗时，不代表端到端延迟。
 - `0004-vdi-power-key-policy.patch` 在 Moonlight Qt 根目录应用。客户端丢弃电源/睡眠键，以及 `Ctrl+Alt+Delete`、`Alt+F4`、`Win+L`、`Win+X`，防止云桌面被关机、重启、锁定或打开包含电源操作的系统菜单；按键不会发送到 Windows、Ubuntu 或麒麟客体系统。
 - `0005-vdi-native-linux-cursor.patch` 在 Qt 根目录应用，为已配置的单座席Linux/X11/2K/绝对鼠标会话创建原生SDL光标，形状/热点/显隐经认证SSH同步，位置不等待视频帧；主机以精确SHA固定的捕获适配器在新连接前去除视频光标。状态过期等故障结束整次会话，恢复原服务后重连。Windows无对应profile，继续原逻辑。安装和限制见[模块说明](../native-cursor/README.md)。
+- `0006-vdi-release-stuck-mouse-buttons.patch` 在焦点丢失和会话退出时显式释放五个远程鼠标按钮，避免一次中断丢失 `BUTTONUP` 后把 Ubuntu 留在“按住拖拽/点击”状态。

 2026-11-03 的现场 RKMPP/EGL 使用独立 PacerRender 线程，诊断会话主线程 render 调用数为 0；因此第三补丁的新调度没有已证明的现场收益，未启用。当时默认客户端恢复至 SHA256 `35de7b1a4ade583823b23b5f2e012307f6d0a3848c8eb97bd6d4de9660afa00f`，该版本现保留作备份。2026-11-05加入0005后现场SHA为 `5d4330f703d7f8e053bc3795ca42bdaf231c9e9dd8ebb00a612013adbcccee03`，Linux profile在获取远端租约前严格校验此SHA；独立光标回归见[实施记录](../../docs/linux-native-cursor-20261105.md)。现场构建保留已有修改并加入0005，尚未重建部署其他任务的0004；构建器0001～0005清洁应用通过与现场补丁集合应分开判断。
