I would say that JPEG compression has partly an impact on the image quality as well. Maybe if there were PNG file instead of JPG, it would be (at least a bit) better...
Another problem is that GDM uses the same image as xsplash and suffers from this as well. I think that "fixing" xsplash itself is not a solution, that image re-rendering would be better choice. Are there any "sources" available (svg, xcf or sth like that)?
