Vuforia SDK Version: 8.0.1 -
Description with steps to reproduce: Setup any project with ARCamera. I used ground plane from core samples
Add button to restart the scene (simple SceneManager.LoadScene())
After few scene loads it results in black screen from ARCamera. The UI, 3D objects, Tracking, etc are working properly, just the background is black.
Random, once it took only 2 times to produce this, sometimes 10 times or more.
Restarting the scene again sometimes fixes the ARCamera (mostly on Android), on iOS when it goes black it will never init properly after next restarts.
App is going to be used at a fair by visitors and the experience will need to be restarted each time
Tested on:
Samsung s8 - restarting again after black screen sometimes fixes
Samsung s6 - restarting again after black screen sometimes fixes
Samsung s4 - restarting again after black screen sometimes fixes
iPhone 7 - black screen persists after first occurance after restarting again -
Development OS (Mac OS X, Windows, Linux): Mac, Windows -
Mobile OS and Version: iOS 12.1.3 Android 8.0.0 -
Mobile Device Manufacturer and Model name: iPhone 7, Samsung S8, S6, S4 -
Do the Vuforia Sample Applications show the same behavior?: Using Core Samples project and tested on Ground Plane scene has the same result
Thanks for the update, iamtheonly. I spent several hours trying to trim down a project to a very small reproducible case. It's really tough and time consuming, the issue presents after 50 sometimes 100 scene restarts, but other times it's right away. Very random. Anyways, since the fix is working, I'm moving on. The issue is definitely there. Hopefully someone else will stumble upon this and be able to create the reproducible case and submit a proper bug report.
