This is really just a cosmetic issue. The window edges (mostly only top left) and window buttons were sharper and clearer in Ubuntu 16.04 und the versions before. The rough window egdges do not appear in all windows, it is especially obvious with Firfox. The impression with the buttons is always present. This is apparent in stock Ubuntu 17.10 on various laptops (Thinkpad x220, Acer Aspire 5253, Macbook Pro late 2010).
