Bug Description
The webcam in Linux has a system that compensates the blinking of lighting under alternate current. Which cannot be perceived by the human eye, but when recorded it flickers the image.
The problem is that depending on the country you are the current blinks either at 50 or 60 Hz. Linux has its frequency set to 60 Hz by default, but using that one in a 50 Hz country renders the system noneffective, getting likely the same flickering as if there was no compensatory system in place.
You can see the effect in the following video:

The computer needs to detect that you are in a 50 Hz country, and change the setting accordingly.
