I know I'm crazy, but it's bugging me.

I can't see any loss of clarity on a 24" iMac - what sites are you seeing this? How can we try to reproduce this? – bmike Aug 9 '11 at 21:21
I can confirm - I've seen lossy quality on a 13" MacBook. – Moshe Aug 21 '11 at 22:26
I can confirm on 2011 MacBook Pro both on the color LCD and when connected to my 27" ACD. It's very noticeable on text links that use the default light blue like on the Apple Community Support Forums. The text appears blurry until the page reloads. – Chris_O Aug 23 '11 at 18:11
Yeah, it's real. I'm surprised there isn't more talk about this. – dot Aug 24 '11 at 1:20
It's bugging me as well. It looks like a screenshot stored in .jpg format. Surprisingly, there're full quality .png preview pictures in ~/Library/Caches/ Previews/ but Safari doesn't use them. – user19745 Mar 7 '12 at 0:46
