The font rendering in iBooks (version 1.0.1) on my Mac (Mavericks 10.9.1) is outright horrible. The text is jagged and rough looking. I've tried changing the font but that doesn't help, it still looks bad. Does anyone have a solution to this problem, or have I just gotten too used to the smooth look of iOS iBooks?
Edit: This is on an early 2008 Mac Pro, on a 22" screen with 1680x1050 resolution, and on a 24" screen with 1920x1200 resolution. Font or font size does not matter. I've only seen the problem in iBooks, not in any other app. Notes and other UI text is fine, it's just the actual text I want to read that's jagged. As a comparison, my mid 2011 27" iMac shows the text beautifully.
