vrOS v0.11.0 Patch Notes

Highlights

Twitch stream alignment is fixed while popped in. Audio enablement is queued for the next patch.

Bug Fixes

• Fixed Twitch live stream video rectangle alignment so popped-in streams render in the right place.
• Fixed Japanese localization in popout overlays and locale sync.
• Made dashboard recenter and reveal commands retry instead of silently failing when HMD pose data is temporarily unavailable.
• Hardened GPU temperature polling during NVIDIA TDR/device-lost recovery so stale NVML handles cannot crash the process.
• Cleared stale texture bridge state across supervisor-driven UI restarts after device loss.

Improvements

• Reduced vrOS and SteamVR compositor contention by skipping unchanged overlay texture submits, lowering render-hot-path log noise, using MMCSS priority for VR/UI threads, and trimming background runtime work.
• Added UI render-thread watchdog logging so GPU stalls are visible within seconds instead of appearing as unexplained log gaps.
• Added compositor timing diagnostics for tracking dropped and reprojected frames.
• Added feature-gated NT-handle/keyed-mutex texture sharing plumbing for future SteamVR compositor synchronization, with the legacy texture path still used by default.
• Added clearer dashboard visibility logging and a dedicated reveal-dashboard command path for recovery workflows.

Other Changes

• Exposed the full OpenVR ETextureType enum needed for DXGI shared-handle support.
• Marked NT-handle sharing as experimental while validation continues.
