Configuration information

Same thing happens with all resolution settings. More than one device has same issue. Hosted with FMS 13.0.1.

The green square seems to be connected to iOS face recognition or auto focus.

Switching to horizontal view removes the green square but crash still occurs.

QR Code only. Scanning other barcode types does not produce this issue.

Crash occurs only in find mode. Could not reproduce in browse mode.

Creating new buttons had no effect.

CNS barcode.
