I encounter similar troubles on Lubuntu 12.04 with an also crappy card: ATI Mobility Radeon HD 2400 with the proprietary drivers installed. As LXDE is pretty much without effects, the way to reproduce and see it there, is when I move windows like mad. It will end up looking similar to George's screenshot.
