Quest 3S: system splash image loads successfully but is not visible in a minimal Unity OpenXR app
System splash images are not visible on our Quest 3S. Only three loading dots appear, followed by the Unity scene.
We reproduced this in a new minimal Unity VR project with only official Unity XR/input dependencies. It contains no company payment AAR, game framework, or original game code.
Environment:
- Device: Quest 3S
- OS incremental: 4069240023000610
- Shell: 209.0.0.568.433
- Unity: 6000.3.22f1
- Unity OpenXR Plugin: 1.18.0
- XR Management: 4.7.0
- ARM64, Vulkan, standard UnityPlayerActivity
- Package: com.suplife.minimalunityvr.splash
- App name: Minimal Unity VR Splash
Steps to reproduce:
1. Install MinimalUnityVR-RGB.apk from the attached ZIP.
2. Wear the headset and cold-launch the app from Unknown Sources.
3. Observe the loading transition before the Unity scene.
Expected:
The four-color image labelled "RGB TEST" appears as the system splash.
Actual:
Only three loading dots appear. The app then enters a blue VR scene with cyan text:
"UNITY VR SCENE / NO LOGO IN THIS SCENE".
Verified:
- The APK contains assets/vr_splash.png, byte-identical to the input image.
- The test image is a 512x512 opaque RGB PNG without an alpha channel.
- A different 512x512 RGBA logo was also tested and was not visible.
- Application metadata:
com.oculus.ossplash=true
com.oculus.ossplash.type=mono
com.oculus.ossplash.background=black
- Shell logs explicitly report:
"Splash logo found for package: com.suplife.minimalunityvr.splash"
"Successfully loaded splash logo texture (512x512)"
- Unity logs confirm XRDisplaySubsystem displayCount=1, running=True.
Several existing games, including Unity 2022 games, show the same visible symptom on this headset. A full headset restart and recentering did not resolve it. A separate stereo splash test in the original game also did not resolve it.
We suspect a system loading-transition or Unity/OpenXR compatibility issue, but have not confirmed an OS regression or the exact affected release. We do not have another headset/OS version available for comparison.
Could you investigate why the successfully loaded splash texture is not presented? Are there any known issues or restrictions affecting system splash images for sideloaded apps?
