I have seen what appears to be the same problem in both 15.10 and 16.04 distributions: windows that sometimes end up away from the visible workspace when using a dual-monitor setup.
I can recover them with 1) alt-space and maximize, or 2) disconnecting the second display. I have a Lenovo Thinkpad X230, with Intel graphics. As #12 suggests, I am now trying to disable the session management plugin through CCSM, and see whether I'll see again the problem. ** Changed in: compiz (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/919437 Title: Lost window, cannot get it back.
