Description Johann G. 2025-11-15 22:04:21 UTC 
SUMMARY
Qrca allows to create QR codes. When I click on the button to create a QR code I notice that the activity light on my camera stays on.

STEPS TO REPRODUCE
1. open Qrca
2. click button to create QR code
3. enter data for QR code
4. quit Qrca

OBSERVED RESULT
The camera activity light stays on all the time that Qrca is running.

EXPECTED RESULT
When switching away from the camera view (step 2), the camera is not used and thus the activity light should go out.
