What do you expect that Cheese should do about your lighting circuit frequency?
Have a setting for changing the webcam line frequency compensation, so there's no flickering.
You really need to watch the above video to understand the issue, otherwise is like talking about a picture which you have never seen.
Such a setting does not belong in Cheese, but may belong somewhere else, such as a (hypothetical) Webcam panel in the control centre, or possibly in gnome-settings-daemon (if it was to be automatic based on location, for instance).
So basically you are suggesting that either you have to create an icon for only one setting in the control panel, or have a list of which setting is the appropriate for every single country worldwide. For me it sounds like over-engineering. That's just an excuse for closing the bug, for not even consider it.
After thinking about this for a while, I have to agree that this setting should belong to somewhere else. Otherwise other services that use the webcam, like online services, cannot be configured too.
Do you know if it could be fixed in a lower system layer than the GNOME desktop?
