AaaaaAA: A Reckless Disregard for Gravity - text drawing problems

r67772, VBox 4.3.12, Guest Additions installed.

Demo can be obtained from http://megagames.com/demos/aaaaa-aaaaa-aaaaaaaaaa-aaaaa-reckless-disregard-gravity-demo-alpha
Game works and renders, but some of the text is unreadable (looks like several lines of text are rendered over each other).

I also attach a screenshot of what the text looks like on Windows.
