I am pretty damn sure that this is and icon theme issue. Using old. incomplete Human icon theme displays blurry icons on many places, not only int Alt+Tab switcher. Try icon theme GNOME-Human from gnome-colors suite where are all icons in all sizes, including scalable version and you will never have this problem again..
