This bug was fixed in the package compiz - 1:0.9.11+14.04.20140423-0ubuntu1
--------------- compiz (1:0.9.11+14.04.20140423-0ubuntu1) trusty; urgency=low [ Ryan Tandy ] * Fix gnome-flashback session starting Unity plugins. Change the profile back after processing settings upgrades. When changing profile, discard existing GSettings wrappers pointing to the old profile. (LP: #1232299) [ Chris Townsend ] * Remove the Number of Desktops option in CCSM as this option confuses Compiz and is really no longer needed since the Horizontal/Vertical Virtual Desktop Size is what is used for determining the size. (LP: #1289820) * Due to some change in Gtk SpinButton, setting the initial value in Adjustment does not work for integers, so now just explicitly set the value after the SpinButton is created.

This can make seem like the user has lost their window and force the user to potentially loose any unsaved works if they can't figure out how to recover the window. [Test Case] To reproduce: * Open CCSM by either typing "ccsm" in the command line or finding it in the Dash. * Go to General Options->Desktop Size. * Enter some number > 1 for "Number of Desktops". * Right click on the decoration of a window and select "Move to Workspace Right". * Watch the window disappear with no trace. After applying this fix: * The "Number of Desktops" option should be gone. [Regression Potential] For Ubuntu running Unity, none identified. Very small chance that some other desktop environment may use this setting, but none of the major desktop environments use it. Original description: When using the 'Move to Another Workspace' right-click option on a window, the window disappears from the current workspace, but is not present in any other workspace. 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.
