Wrong video preview orientation on landscape

Reproducible on the Recorder example.

If the app starts at portrait mode and then moves to landscape mode, the preview video becomes messed up. View attached "portrait.jpg" and "landscape.jpg".
If, on landscape mode, the preview is reset (the camera switch turned off and on) becomes fine until it moves to portrait again.
The recording is not affected. When a recording starts will reset the preview before, and it will preview right during the recording. The final output video file is also ok.
