    Description

      Linux Ubuntu 22.04.4 / Wayland

      Qt Creator 14.0.2

      Device: Raspberry Pi4 64 bit with Qt 6.8.1 

      Steps to reproduce:

      1. Open camera QML.
      2. Notice the latency of the camera view.
      3. Start recording.

      Expected: There should not be any lags in the recording.

      Actual: Camera view freezes, and there is a very low frame rate - see attached, the cube should spinning smoothly. 

      Reproducibility:  100%
