I've been having similar problems when smooth scrolling but not when fast scrolling, so presumably it has to do with some sort of acceleration problem in the driver. I've been having these problems with every version of Lucid so far. I did not have them with Karmic. I can trigger video corruption reliably by grabbing the scroll bar in firefox or chromium and moving it quickly. Once corruption occurs it becomes prevasive.
