No glow effect on expo Compiz plugin.

Hello!!

I've an issue with Compiz's expo plugin, there isn't the orange glow effect which shows the current workspace.

If I run "dconf reset -f /org/compiz/" and "setsid unity" fixes the problem temporarily because when I reboot the laptop the problem is still there.

Thank you very much!! :)
