Hi,

I'm experiencing an issue where all RealityView content disappears when the user selects "Lock In Place" from the window management menu (long press on close button). "Follow Me" works correctly and this happens in Testflight builds only not reproducible when I run locally

I have reproduced this with a minimal project containing nothing but a simple red cube — no custom anchors, no app state, no dependencies.

Steps to Reproduce:

Open an ImmersiveSpace.
A red cube is placed 1m in front of the user via RealityView.
Long press the X button on any floating window

Select "Lock In Place". The cube disappears immediately.

Expected: Cube remains visible after window is locked

Actual: Cube disappears.

Minimal reproducible code:

    var body: some View {
        RealityView { content in
            let cube = ModelEntity(
                mesh: .generateBox(size: 0.3),
                materials: [SimpleMaterial(color: .red, isMetallic: false)]
            )
            cube.setPosition(SIMD3<Float>(0, 1.5, -1), relativeTo: nil)
            content.add(cube)
        }
    }
}

Device: Apple Vision Pro

visionOS version: Vision OS 26.2 (23N301)

Xcode version: Version 26.3 (17C529)

Is this a known issue? Is there a recommended workaround to preserve RealityView content during Lock In Place transitions?

Thank you!

Hey @Kunal07,

Thank you for filing your Bug Report (FB22290781) and including a sample project and a video, however, I'm unable to reproduce this bug. Whenever I was in the immersive space the red cube was there. I tried running the app in the Release and Debug configurations.

In the video I see the following:

at 00:10, you lock the window and the cube does not disappear.
at 00:18, you close the immersive space and the cube disappears with the immersive space.
at 00:27, you reopen the immersive space and the cube appears.

Your sample app provides a fully immersive space. You are in the immersive space when you no longer see passthrough. It might be more clear if you replace the static "Open Immersive Space" button with ToggleImmersiveSpaceButton(). Can you do this and reproduce the issue with a video?

If you're able to reproduce this, a video and a visionOS Sysdiagnose would be very helpful.

Thanks,
Michael

Hi Michael,

Thank you for looking into this. To clarify, this issue is not reproducible when running locally (Debug or Release). It only occurs in TestFlight distribution builds.

In our production app as well as the minimal sample project, the behavior is consistent — the bug only appears when installed via TestFlight, not when run directly from Xcode.

Regarding the video - at 0:31 you can see the cube briefly disappears after Lock In Place. That is the moment we are referring to.

Could you please try the following:

Archive the sample project
Upload to TestFlight
Install via TestFlight on the device
Reproduce the Lock In Place steps

I am confident it will be reproducible in that configuration. I am happy to provide another screen recording specifically showing this if that would help.

Please let me know if you need anything else.

Thanks,

Kunal

Hi Michael,

As requested, I updated the sample app to use ToggleImmersiveSpaceButton instead of a manual open/close button.

I rebuilt the app, distributed it via TestFlight, and reproduced the issue on Apple Vision Pro.

The issue still occurs consistently.

Attachments:

Screen recording demonstrating the issue - TestFlight distributed Build.
Sysdiagnose captured after reproduction of the issue.
Updated sample project.

Steps to reproduce:

Archive and upload a build to TestFlight.
Install the application via TestFlight.
Tap "Show Immersive Space".
Lock the window.
Tap "Hide Immersive Space".
Tap "Show Immersive Space".
The red cube is missing and even immersive space and window disappears for a brief moment and then appears.

Apple Vision Pro
visionOS 26.0

Xcode:

Version 26.3
