Thanks Stefan, now I can reproduce the problem. 1. Boot the system 2. Capture an image with capture-example from v4l2-apps. Then I have the shift as in the picture above on the *first* device open, if I open the device again and capture a second time, without rebooting, the picture is fine. I'll let you know if I find more clues of what is causing this behavior.
