I've been looking at this and it seems this occurs when setting ccsm->General Options->Desktop Size->Number of Desktops to some value other than 1. I'm thinking that setting may not be needed anymore, but I still need to investigate.

It effectively is no longer accessible, though it can still be killed. Disabling workspaces does not cause the lost window to reappear, but setting the number of desktops to 1 in CCSM > General Options > Desktop Size > Number of Desktops does the trick and the window reappears. I am using Ubuntu 14.04 (latest updates as of 2014-03-07) and NVIDIA proprietary drivers. I do not experience this problem on Ubuntu 13.04.
