I've determined that this is pretty reliably reproducible when using chromium by loading google+ and rapidly scrolling up and down using the touchpad. I'm not sure whether or not it's specifically tied to chromium however. I also saw it earlier when scrolling through a spreadsheet in Calc, although I haven't been able to reproduce it and I did have chromium open at the time.
