Inline comments:
In `@app/src/main/cpp/xrimmersive/xr_immersive.cpp`:
- Line 1099: Update submitWindowsProjection so it distinguishes “no Windows
projection was submitted” from an xrEndFrame failure: once xrEndFrame has been
called, return success to prevent the caller from entering the fallback path and
ending the frame or rendering again. Preserve the existing false result only for
the path that does not submit a frame.
In `@app/src/main/cpp/xrimmersive/xr_windows_transport.cpp`:
- Around line 556-563: The pollEye method must transfer safe caller-owned
ownership for every returned eye buffer: acquire the AHardwareBuffer reference
and duplicate each dma-buf descriptor before exposing the EyeFrame, while
preserving the existing latestClaimed_ state update. Update the presenter import
paths using createImageFromHardwareBuffer, createImageFromDmabuf, and
uploadLinearDmabufToTexture to release these references and descriptors after
import or cache lifetime, including all failure paths.
In `@app/src/main/java/app/gamenative/ui/screen/xr/ImmersiveXrActivity.kt`:
- Around line 1217-1219: Update the flatPresentationSuspended branch in
scheduleNextCapture so it submits the refreshed overlay bitmap via the existing
nativeSubmitFrame path before scheduling the retry; do not gate this submission
on directRenderActive, ensuring refreshOverlayLayer overlays remain current
during stereo presentation.
In
`@app/src/main/java/app/gamenative/ui/screen/xr/windows/WindowsVrControlServer.kt`:
- Line 23: Move lastFrameSerial from shared server state into each client
connection handler so frame progression is tracked independently per client. In
the FRAME_SYNC handling, capture one local WindowsVrRuntimeSnapshot and pass
that same snapshot to waitFrame() and the three response formatters, avoiding
repeated snapshots.latest() calls and ensuring all response data comes from one
frame.
In
`@app/src/main/java/app/gamenative/ui/screen/xr/windows/WindowsVrDiagnostics.kt`:
- Around line 21-29: Make the diagnostic write in WindowsVrDiagnostics non-fatal
by catching failures from appendText and related formatting or trimming
operations, while preserving the existing diagnostic content when writing
succeeds. Ensure beforeWineSystemSetup can complete and setupWineSystemFiles
still runs even if diagnostic file I/O fails.
In
`@app/src/main/java/app/gamenative/ui/screen/xr/windows/WindowsVrPayloadManager.kt`:
- Line 113: Update the OpenComposite installation flow so its rollback
transaction is registered before any backup, owner, DLL, or INI mutation, rather
than only after adding the directory to openCompositeDirectories. Ensure the
rollback handler restores or cleans up every partial state when any write fails,
including failures during the INI write, while preserving normal successful
installation behavior.
- Around line 199-205: Update recoverSharedPayload() to derive the expected
payload target from the fixed mutation name and container, rather than trusting
the path read from the .target recovery record. Compare the canonical recorded
target with that expected target and reject mismatches before atomicReplace() or
deletion; retain recovery only for the fixed targets validated by
validateSharedTarget().
In
`@app/src/main/java/app/gamenative/ui/screen/xr/windows/WindowsVrSnapshotProvider.kt`:
- Line 40: Update the snapshot publication in WindowsVrSnapshotProvider so
nativeWaitWindowsFrame only assigns latest when its handle still matches
activeHandle, rejecting results from detached sessions. Ensure every attachment
also clears latest, while preserving the existing detach behavior.
In `@app/src/main/java/com/winlator/renderer/VulkanRenderer.java`:
- Around line 73-80: The flat-presentation transition is updated in separate
owners, allowing PresentExtension and VulkanRenderer to observe inconsistent
states. In VulkanRenderer.setFlatPresentationEnabled and
XServer.isFlatPresentationEnabled, use a single shared owner or synchronize the
transition and every read so applyFlatPresentationGate changes become atomic;
update both affected sites:
app/src/main/java/com/winlator/renderer/VulkanRenderer.java lines 73-80 and
app/src/main/java/com/winlator/xserver/XServer.java lines 109-114.
- Around line 79-80: Update the flat-presentation re-enable transition around
queueSceneUpdate and xServerView.requestRender to republish all mapped drawable
contents before requesting the render. Reuse the existing drawable-content
publication mechanism, preserving the current render-list rebuild behavior and
avoiding changes to unrelated presentation paths.
In `@app/src/main/res/values/strings.xml`:
- Line 2481: Update the xr_windows_vr_toggle_desc string to explicitly include
D3D11 among the required components, while preserving the existing guidance
about arm64ec Wine, DXVK, and flat immersive-screen fallback.
In `@app/src/main/windows/openxr_runtime/gamenative_actions.c`:
- Around line 259-265: Update gamenative_locate_space to compose the selected
action pose with space->offset: rotate the offset position by the action
orientation before adding it to the reported position, and multiply the action
and offset orientations for the reported orientation. Preserve the existing unit
conversion and use the poseInActionSpace data stored by
gamenative_create_action_space.
- Line 115: The action-set destruction loop must not clear action records still
referenced by action spaces. Update the action lifetime handling around
gamenative_create_action_space, gamenative_locate_space, and both destruction
paths so referenced gn_action state remains allocated and unchanged until its
dependent spaces are destroyed or the session ends, preventing slot reuse from
changing an existing space’s bindings.
In `@app/src/main/windows/openxr_runtime/gamenative_control.c`:
- Around line 18-19: Update initialize_control to call WSAStartup before
InitializeCriticalSection, only initializing control_lock after Winsock setup
succeeds. In both InitOnceExecuteOnce callers, check its return value and exit
before entering control_lock when one-time initialization fails, preventing
retries from reinitializing the critical section.
In `@tools/build-xr-payload-macos.sh`:
- Line 40: Update the runtime compilation commands near
gamenative_openxr_runtime.c to include all implementation units required by the
canonical build: gamenative_control.c, gamenative_actions.c, and
gamenative_dxvk.c, while preserving the existing output and definition-file
handling.
- Around line 24-25: Update the archive download and extraction flow in the
macOS build script to verify the OpenXR release archive’s SHA-256 digest before
passing it to tar. Download the archive to a temporary file, validate it against
the expected pinned digest, and only extract after verification succeeds;
preserve the existing release URL and include path.
In `@tools/stage-wine-xr-bridge.ps1`:
- Line 12: Add an explicit dependsOn("buildModernXrNative") relationship to
stageWineXrBridge so native XR bridge compilation completes before staging
invokes verify-arm64x-wine-pair.ps1. Preserve the existing staging command and
verification behavior.

Keep frame state per client and format FRAME_SYNC from one snapshot.
The server runs client handlers concurrently, but all clients share lastFrameSerial and snapshots.latest(). One client can advance another client's serial. Another client can replace latest between waitFrame() and the three formatting calls. The response can contain timing, views, and input from different frames.
Store the frame serial in the connection handler. Pass one local WindowsVrRuntimeSnapshot to all four response formatters.

OpenXR 1.1 XrActionSpaceCreateInfo poseInActionSpace locate action space pose composition specification
💡 Result:
In OpenXR 1.1, XrActionSpaceCreateInfo is a structure used to define the creation of an action-based space via the xrCreateActionSpace function [1][2]. The poseInActionSpace member is an XrPosef that specifies the position and orientation of the new space’s origin relative to the natural reference frame of the pose action [1]. Key technical details regarding this structure and its usage include: Structure Definition: The XrActionSpaceCreateInfo structure contains the following members: type: The XrStructureType (must be XR_TYPE_ACTION_SPACE_CREATE_INFO) [1]. next: A pointer to the next structure in a structure chain or NULL [1]. action: A handle to a pose action (created with xrCreateAction) [1]. It must be of type XR_ACTION_TYPE_POSE_INPUT [2]. subactionPath: An optional XrPath used to specify the subaction binding, or XR_NULL_PATH [1]. poseInActionSpace: The XrPosef defining the transform of the new space's origin within the action's natural reference frame [1]. Usage and Locating Spaces: Once an action space is created using xrCreateActionSpace, the application can determine its pose at a specific time by calling xrLocateSpace [3][4]. This function provides the physical location of the created space relative to another specified base space (such as a reference space like STAGE or LOCAL) [3][5]. When locating, the runtime handles the composition of these spaces [5]. If the action space is dynamic (e.g., tracking a motion controller), passing an updated time to xrLocateSpace allows the application to retrieve the updated relative pose each frame [5]. The runtime ensures that even if tracking is lost or inferred, valid (though perhaps non-tracked) location data is returned, provided a relationship can be determined [3]. For authoritative documentation, please refer to the official OpenXR 1.1 Specification [6][7].

Compose poseInActionSpace with the selected action pose.
gamenative_create_action_space stores info->poseInActionSpace in space->offset, but gamenative_locate_space only adds the offset position and leaves the action orientation unchanged. Rotate the offset position by the action pose and multiply the orientations. Otherwise, aim or grip spaces with non-identity offsets can report incorrect poses.

Microsoft InitOnceExecuteOnce callback returns FALSE initialization remains incomplete subsequent call retry documentation
💡 Result:
When the callback function provided to InitOnceExecuteOnce returns FALSE, it indicates that the initialization has failed [1][2]. The state of the one-time initialization block is not marked as initialized [2], and the specific call to InitOnceExecuteOnce that executed the callback returns FALSE to the caller [1][3]. Subsequent calls to InitOnceExecuteOnce for the same initialization block will not be permanently blocked by the previous failure [4][5]. Instead, the system allows the next waiting thread (or a subsequent caller) to attempt the initialization again [1][5][3]. This cycle continues until a callback eventually returns TRUE, at which point the block is marked as initialized, and all subsequent calls will return TRUE immediately (without re-executing the callback) [1][5]. In scenarios where the initialization might fail intermittently, the recommended pattern is for all threads to continue calling InitOnceExecuteOnce until it returns TRUE [1][3]. For reporting specific error details when the callback returns FALSE, you should call SetLastError within the callback function before returning [2][6]. The InitOnceExecuteOnce function itself does not clear or overwrite this error code, allowing the caller to retrieve it via GetLastError if the function returns FALSE [6].

Handle failed one-time initialization before using control_lock.
initialize_control initializes control_lock before WSAStartup and returns FALSE when WSAStartup fails. Both InitOnceExecuteOnce callers ignore that result and enter control_lock. A later call can retry the callback and initialize the same critical section again, which can corrupt synchronization or crash. Call WSAStartup before InitializeCriticalSection, and return before using control_lock when InitOnceExecuteOnce fails.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Add dependsOn("buildModernXrNative") to stageWineXrBridge. verifyModernXrPayload schedules both tasks without ordering them, and no task input/output wiring adds an implicit dependency. If staging runs first, Resolve-Path cannot find gamenative_xr_unixbridge.so, so the clean Windows payload build fails.

Consider keeping the generated .so in build/generated (git-ignored, wiped by clean) and copying only into the tracked jniLibs as an explicit, intentional step rather than on every build.</comment>

Description
Merges
vr-support-perf(TheReal-Flo's PC-VR bridge plus our performance work) into master, with Windows VR made opt-in so existing immersive games are unaffected. Beat Saber verified in stereo on a Quest 3S from this branch (commit a3e2704).What the bridge does: a Windows OpenXR runtime DLL inside the container talks to a Kotlin control server and ships eye frames through a wine unixlib to the immersive compositor, which submits them as stereo projection layers. Not every VR title works yet; the runtime needs arm64ec Wine, DXVK and D3D11.
Changes on top of the branch:
app/src/modernXr/assetsandapp/src/legacyXr/assets.libxrimmersive.sois rebuilt from the branch source and committed for both XR flavors. The branch'ssetSrcDirshad dropped the tracked jniLibs folder, so non-Windows builds shipped no compositor; the source set now lists it. All payload scripts write into the tracked folders.Recording
Verified live on Quest 3S: Beat Saber in stereo, head tracking, menu at ~56 fps. See the vr-support-perf branch for earlier captures.
