Running Xinerama on 10.04.3 with triple monitors across two GPU's... I can reproduce this bug on demand within seconds of a fresh boot by simply dragging a selection box on the desktop up and down the seam between either pair of monitors (0 & 1 or 1 & 2).
During normal workday use, this bug renders my entire system unresponsive several times per day.
