I did discover this nearly by chance, so please check if you have issues like that crawling around your Mac. It seems to affect some kind of layered PDFs, making them almost worthless. Worst part : it's still broken, but "bearable" on Tiger, and no problemo on XP(Foxit PDF Reader) I did try : Preview, Skim, Yep, on both 10.4 & 10.5 (btw even QuickLook was consistent with other app's results) So I suspect it's Core Image's glitch ? This is Preview in Leo (10.5.3) (P.S. this file is made by older InDesign 2.0.2, but it does render perfectly on Win XP, not even frames around pictures show) This is Preview in Tiger. At least it shows 90% of text in question ..... On XP everything is perfect, No garbled text, Even white frames around pictures (folder i.e.) mostly gone. It seems, after some investigation, that I do have more than few files with troubles like that. Chances are, many of us can have this problem .... I did search for this glitch on couple of forums, but couldn't find anything. So, Please, do yourself a favor - check if you have similar results. I'll include troubled file in question, just for testing's sake, but if you look hard, you'll probably be able to find yours. P.S. PDF file is a bit bigger (372KB) than forum allows, so I've split it in two Rar's, but had to rename them with Zip extension, as this forum doesn't accept them. Rename them back to Rar, and you'll be fine with free UnArchiver for example. What ? Nobody has this issue ? Nobody has time to verify my heresies ? And condone my doubts in holy 10.5 ? Can you just try it out, to see for yourself. This is a BIG ISSUE, and it has no place on Mac OS X, which is lauded for native PDF handling. If WE don't rise it as the Issue, then it won't be fixed !!! P.S. maybe I'm just wrong, and it's just user generated glitches on two Macs I have access to. OK, I'd be glad & relieved if you'd point it out, and help me solve it, and restore my faith (and peace) BTW.
