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).
