As suggested in comments, converting .jpg to a .png file fixed the issue.
.png is a more native file format for Linux and .jpg is a more native file format for Windows. That said the file conversion software may have removed “noise” from the .jpg file when converting it to .png format. If there was “noise” what it was is anyone’s guess. If you are in a similar situation and you must have .jpg file format you can still convert it to another .jpg file with a bit of file compression and may also be successful.
