## Executive Summary
The last release broke UMU for a lot of people and this new Hotfix should fix it. Hopefully our last hotfix before the next Major release. What's Changed fix: Don't nest umu if steamRuntime ends up enabled on a non-native game by @CommandMC in #5894 Full Changelog : v2.22.2...v2.22.3

## Architectural & Systems Analysis
From a graphics pipeline, kernel sub-system, and runtime compatibility perspective:

- **Translation Efficiency:** Minimizing DirectX/Vulkan mapping overhead (DXVK, VKD3D-Proton) delivers deterministic frame times.
- **Kernel Synchronization:** Integration of wineserver optimizations with fsync/futex primitives eradicates multi-threaded bottlenecks.
- **Engine Neutrality:** Open engines like Godot provide a genuinely vendor-independent development target.

## Impact on the Open Ecosystem
Solidifies Linux as an uncompromising, tier-one operating system for high-performance interactive 3D computing.
