Do web pages in Google Chrome look odd to you? That’s because the latest build for Mac OSX has turned off subpixel rendering, apparently.
At the “macro” level, fonts as rendered by Chrome look thinner. Subjectively, they are not as legible. They also look slightly washed out.
At the “micro” level, if you magnify the Chrome and Safari snippets a few times, you will see that Safari uses subpixel rendering: loosely speaking, this means that the “edges” of character shapes (glyphs) are actually drawn in different colors, not just different tones of grays. On the other hand, Chrome seems to have inexplicably switched to purely grayscale rendering of fonts.
