Weird XP desktop background.

I know I probably should have posted this in the computer forum,but it is not really computer problem.

Windows XP has a number of desktop backgrounds that one can choose to display as their background.

One of them is called Red moon desert.

The moon in the desktop background is upside down.

Has this been noticed before? I know I maybe late to this realization since XP has been out for a long period of time but it just seems so weird.

That really doesnt matter
