Text Rendering On New Air

First post for me but I have been reading the MacRumors forums for years. We just got a 1.8 Air with the SSD drive for our company's CEO. Our IT Administrator and myself were playing around with the Air testing out the gestures you can do with the trackpad. After zooming in and out of an image repeatedly the text in the OS is no longer rendering properly. An image of the problem is attached. Restarting, relaunching the Finder, zapping the PRAM, and resetting the power management unit do not fix the problem. I am wondering if there is a problem with the driver for the graphics, an actual hardware problem, or something else in the OS that we have not tried. Has anyone encountered this and have a solution? System has 10.5.2 and the Leopard Graphics update installed.

Thanks
