Description
In the QML Camera Example from Qt/Examples/Qt-6.2.2/ only a few first frames get rendered in the preview although the camera is still running. Also, it takes a lot of time to open a camera. Happens in 100 % of cases with MBP built-in camera. The example works as expected on macOS 11. Camera and microphone permissions were granted.
The last log I could see from debugging
