Totally fair question. Sorry for not being more specific. All multi monitor and docking/undocking broke in seemingly random ways. That's despite giving state transitions ample time (ie. not detaching a screen and then immediately closing the laptop to put it to sleep).

Also I was bit by the bug that somebody else mentioned here: the panels would disappear with sweet reliability. If I remember correctly, this was a bug that would hide the existing dock. So if you simpy recreated it, you'd have two running side by side, and so on.

There was more but I don't remember specifics. The screen issues were enough to be a big practical problem for me.
