Lines Appearing On Wallpaper?

Recently however there is a white line that is going through the wallpaper. and now add to that a red line. At first i thought it was my moniter but the lines only go through the wallpaper, they dont appear in videos, when im browsing the internet, or when in game. They are only appearing on that wallpaper. I can change the wallpaper and the lines aren't there. If i change back they are there. So i figured that my image might be corrupted so I went online and looked for the same picture again. I found it twice and both times the lines were there on the picture. Not after I downloaded it, as I found the picture online, on the webpage, before redownloading.
