Font in Preview blurry

In Yosemite, when I look at a pdf file in Preview the fonts are blurry compared to Mavericks. The upper image below is a screenshot using Mavericks, and the lower one is from Yosemite.


I tried fiddling with LCD font smoothing in preferences, and restarting, but nothing changed. Anyone else having this issue, and maybe found a solutions?

Dear Stuart Field and concerned Apple staff,



Apparently it is because the anti-aliasing algorithm used by Preview.app in Yosemite is incorrect.

The same problem has been raised and discussed recently on other sites including Redditand StackExchange.

A comparison of the same PDF viewed in 10.9 and 10.10 can be seen below (images taken from this post).

10.9 (correct and beautiful with colorful shadow):

and on 10.10 (weird, grey shadow):

Presumably this bug is coming from the incorrect adjustment for Mac family with retina display.

Note that this bug does NOT happen in Safari, which is quite amusing.



Sincerely,

Leo

Seems in OS X 10.10.1, Preview 8.0 (859), that the text is crisp and clear when opening, but gets blurred when for instance adjusting window height. When slightly altering the window width, text looks sharp again. As if the text is initially rendered like it should, but then for performance reasons is translated to an image in memory. The translation occurs in a flawed way then.
