Improving font display: OO 2.3.0 under Linux (Ubuntu 7.10)

Is there a way to improve the font rendering when editing a document in OOWriter?
Fonts that appear crisp in other applications, are jagged and with odd kerning in OO.
I am running OO 2.3.0 under Ubuntu 7.10. Attached is an example of a OO document next to its PDF export displayed with the AdobeReader.
