Out of place pixelated area on back of Lacrosse Roadhog skin

I noticed that there is an out-of-place pink and cyan pixelated area on the back of Lacrosse Roadhog’s white collar; this can be seen in-game as well as on several different videos/other users’ computers. It looks a bit annoying to look at, and would be great to have this area on the skin fixed (should be relatively easy.

The described area can be seen here:

Thanks in advance, and let me know if any further info is necessary!
