There is a bug in windowxp image and fax viewer.

If an image contains an image with an RGB value of 0xF7F7F7, the image area is heavily colored in the image and fax viewer. Put it in the drawing program for comparison and you can see it (you can also see it without comparison, just to have a physical evidence ).
In a simple example, select the view mode as detailed information in the resource manager of XP. Then, the base color of the sorting column is 0xF7F7F7. After screenshots are taken, we can verify what I said.
At first, I suspected that my monitor was abnormal or my eyes were abnormal. Later, I opened the drawing program and the Image Viewer at the same time to believe that it was an XP Bug.
