Visio 2010 PDF issue

[rickscr]

I'm having a weird problem when saving/exporting my Visio document as a PDF. The shapes in the PDF come out with jagged edges that don't show up in Visio. If I look closely, the same problem is present when I print from Visio.  Has anyone run into this before?
I've attached sample screenshots from the PDF and from Visio.

Here is another example.

One more. The letters are part of a logo and are not text.

Have you tried another PDF tool than the one integrated in Visio?

Yes, I also tried printing to PDF.

I have found a solution for now. There must have been something wrong with the file, because when I started from scratch, the problem went away.
