I recently learned about subpixel rendering, and was fascinated by how it works. On my mac, I can turn it on and off in system prefs - general - LCD font smoothing, which implies to me that it is handled by the OS, not by individual applications. My first question is, is this assumption correct? How is subpixel rendering handled? On my friend's computer with a retina display, the LCD font smoothing did not seem to add colors to text like on mine. Do retina displays handle it differently?
Since I was curious about the process, I tried turning it off and back on again. I noticed that some applications took a while to accept the changes, but restarting usually applied them. However! I've turned LCD font smoothing back on, and it works everywhere except this website. This is true in Chrome and Safari. What's the deal with that? Did I mess something up, or does the website somehow prevent subpixel rendering? How and why?
