The shadows of each letter overlap the previous letter. That’s because I’m drawing one letter at a time. So for example in the fl, I draw the f’s letter, outline, and shadow, , and I noticed another issue. The shadows of each letter overlap the previous letter.

Last timeLast time I was looking at letter spacing with my renderer to see how it compared to Google Chrome on Mac. But while doing that I noticed that their antialiasing looked nicer than mine. So I tweaked parameters, including antialias edge width, gamma, and threshold bias. I was looking at letter spacing with my renderer to see how it compared to Google Chrome on Mac.
