Hmm, I'm thinking turning off the monitor is the root issue here. Compiz does not always handle monitor hotplugging very well which is what happens when powering off the monitor.
A few more questions to help me narrow this down. 1. Are you using more than one workspace? If so, what is your workspace geometry like, ie, 2x2 workspaces? If you don't have workspaces enabled, could you try enabling workspaces when this issue occurs and see if it shows up in one of the workspaces. 2. Are any of the windows on your second monitor maximized? 3. You say "monitors", implying you turn off more than one monitor. Is this something like a dual monitor desktop system? As far as the monitors not powering off when they are supposed to, I think that is either an issue in power management or the kernel and not in Unity/Compiz. Lastly, I've been doing some work with windows getting shuffled around when removing/adding a monitor, so if you feel a bit adventurous, you could try a test Compiz package I have that could (hopefully) fix this issue. Try adding https://launchpad.net/~townsend/+archive/compiz-test and see if it helps and report back to me.
