If you need a testbed just install gnome-session-flashback in a 14.04 virtualbox vm.
I tried using it and had the exact same issues as on my desktop. I used the latest virtualbox from the 14.04 repos/no usb/ no guest tools It shipped broken. I read in another place that there was a new compiz in staging with large feature changes. Could this relate? -- You received this bug notification because you are a member of DX Packages, which is subscribed to compiz-plugins-main in Ubuntu.

When I'm switching workspaces, it occasionally locks up (becoming more frequent). Most of the time, I'm going from the current one down (Ctrl+Alt+Down Arrow), and it freezes mid slide. Typically, I'm able to correct things by backing out to a terminal then returning (Ctrl+Alt+F1, pause, Alt+F7), but sometimes when I return the dual screen setup acts as one large screen (windows are stretched to the full width of both screens) and many of the windows collect on the first workspace.
