a part of the Tello.CAMERA_DOWNWARD output is green

[SKLD]

Hello,

I just received a tello drone. I connected it with my pc to see what it is made of and what you can do with it.

However, I just noticed that when I change the Tello.set_video_direction() to downward camera, part of the video feedback is green.
As you can see in the attached image.

Some of you have the same problem?
Any idea of its origin?
How to fix it?

Thanks in advance for your feedback.

Is there an easy way to check for this? Is it possible that this is causing reduced position stability in later Tellos?
