Comment 11 for bug 919437

Just ran into this after a reboot that hung so I reset my machine.

Started Sublime Text 3 in Unity, no window. Can alt-tab to an icon, but nothing is there. Super+w shows nothing. Log out and back in, same problem.

In Cinnamon I started Sublime and it appeared in the top left of my left hand monitor. Dragging the window was buggy the first time, but on the second attempt it moved to the middle monitor fine. Logged out and back into Unity and Sublimed loaded fine with a visible window.

This seems like a window manager not detecting corrupt placement cache problem, not a compiz issue, since both desktops render using Compiz, right? Perhaps Unity needs some sanity checking for if a window is supposed to be visible on one of its desktops, make sure that it is.
