This happens in Windows and Linux, with both retail Leap Motion and DevKit units. If "Rectify" is off, then cameraControlExample.py works perfectly for me. As soon as I enable "Rectify", I get only black frames. This is the reason why stereoExample.py does not work either - it uses image rectification. I'm using Python 3.8.6 and opencv-python 4.4.0.44. I also tried opencv-python 3.4.11.43 (latest 3.4 release) but the result is the same - "Rectify" just makes everything black.

Any ideas how to fix this?
