Black/glitched screen after return to app

October 13, 2019 - 6:33am #1

Sometimes on some devices (Android, iOS), after call or any other source of app losing focus, vuforia camera becomes black or repeats some ui graphics rendered over (other cameras work fine, it's possible to see thing rendered by other camera but under is this glitch). What can be a source of problem?

Hi,

Unfortunately I don't have the device to test the behavior. This being said, I've tested on a Huawei Pro and was not able to reproduce the issue.

Could you please try to reproduce the issue using the core sample app and let us know the outcome?

Thank you.

During runtime, when app loses focus, when someone calls or just other app is selected to foreground by user
