(Get the code!)
I've tried this on my own Lenovo Thinkpad X230 (also a 2306CTO), and I can't reproduce the issue at all. I've tried both the dock's full-sized DP connector and miniDP on the laptop itself (undocked), both work with no issues at all, and no artifacts on the external screen (or the panel, for that matter).
I have no idea what causes this. Perhaps we're dealing with a monitor that claims to support some resolutions it doesn't really like? The monitor I use is a fairly good Dell P2210, but doesn't apparently confirm to EDID 1.3 (but still works correctly).
