Ugly reports in gnucash

After upgrading to the latest gnucash, I find that my reports are all unreadable. Outlined fonts, no bars showing up in bar charts, etc. For example: http://www.eng.uwaterloo.ca/~jlschofi/screenshot.png If I print the report to a PDF file and open in Preview, it looks fine. And in previous versions of gnucash it was normal. Anyone else having the same problem and/or know what's causing this? Thanks, James
