One more data point: When docking the laptop while running, the problem doesn not occur, apparently even after a subsequent suspend and resume cycle.

This is most noticeable when running fast terminal outputs or dragging windows. Restarting the X server makes the problem go away until the next suspend or output switch. Unfortunately, I have not been able to narrow down the exact circumstances that cause it to happen, but I've never seen it on the internal LVDS-connected screen of the laptop, and never directly after starting X. I'm suspecting this is related to SNA; I'll try using UXA for a few days and check if the problem manifests again.
