So here is yet another plea for designers to stop “fixing” WebKit
font smoothing by disabling subpixel rendering. Feel free to use
it on light text on dark backgrounds, feel free to use it to fix
custom font rendering on Windows or to style specific bits of text
on the page to make it look more slender, but for main portions of
text where readability is paramount please leave the default
setting alone and let the operating system handle the smoothing.
