DisplayXR Runtime v2.32.0

Highlights

Stereo cameras for XR_DXR_stereo_camera (#1846): a new vendor-neutral UVC side-by-side stereo camera source on Windows (Media Foundation), opt-in via %LOCALAPPDATA%\DisplayXR\stereo-cameras.json, with hardware MJPEG decode + GPU scale and a pipelined readback ring — hardware-verified on a SpatialLabs Eyes camera at 60 Hz with rows aligned (V4L2 stub on Linux).
Also: a native Metal backend for the macOS weave service (with xrWeaveSnapWindowRectDXR routed to the Metal DP), multi-screen segments on D3D12 and on the IPC/service path (multi-screen M6 + M3), macOS monitor enumeration + runtime-owned phase-snapped window drag/resize, in-process D3D11/D3D12 sessions reaching the service's lift (ADR-049), monitor physical size from the EDID on Windows, and the D3D12 cube test apps' sRGB colour fix.

Features

• feat(stereo-camera): vendor-neutral UVC side-by-side stereo source (Windows MF; V4L2 stub)

• feat(test-apps): cube_handle_d3d12_win renders per-segment views (multi-screen M3)
• feat(oxr): per-segment views for IPC sessions on Windows

• feat(d3d11): segment a straddling window under the weave-on-scanout split (multi-screen M6)
• feat(metal): runtime-owned, phase-snapped, atomic window drag + resize on macOS (ADR-050) (#1875)
• feat(metal): multi-screen segments on macOS — per-display Metal DPs + per-segment views (#1873)
• feat(os): macOS monitor enumeration — CoreGraphics displays + IOKit EDID feed the claim registry (#1872)
• feat(lift): in-process D3D11/D3D12 sessions reach the service's lift over a lift-only connection (ADR-049) (#1867)
• feat(lift): app rig drives lift viewpoints + auxiliary metric depth on the lift thread
• feat(lift): XR_DXR_lift v3 API + DP contract — app rig viewpoints and auxiliary metric depth

Fixes

• fix(stereo-camera): UVC GPU path — no letterboxing; pipelined readback ring
• fix(weave): macOS weave review fixes — origin logging, mixed-scale panel pick, Metal DP retry
• fix(test-apps): D3D12 cubes decode authored colour for an _SRGB RTV (ADR-044, #1882) (#1885)
• fix(os/win32): fill monitor physical size in mm from the EDID (#1877)
• fix(plugin_loader): don't skip the claim sweep when a DXR_SCREEN_PLUGIN pin names another plug-in (#1874)
• fix(pin-bump): watch xrt_dp_lift.h in the features gate (#1871)
