Howdy,

I can confirm the problem you are seeing. Since the same pdf displays differently in PDFKit previewers (e.g., TeXShop and Preview --- incorrectly) while displaying correctly in Adobe Reader and (almost correctly --- transitions not smooth) in TeXworks I'd say it is a PDFKit problem. On the other hand, the fact that the latex->dvips->ps2pdf produced version appears correctly in all previewers leads me to a possible edge problem in tikz or pdftex. Sigh...

This is using MacTeX(TeX Live)-2009 with all updates.

Good Luck,
