I confirm this as it happens to me quite a lot! But in my case, if any application is in fullscreen mode (e.g. skype, QtCreator, Android Studio...) and if I try to switch between wrkspaces by ctrl-alt-arrow keys, compiz cpu utilization goes to 100% and there is no escape from it! only solution is hard reset...going to a terminal does not always work in a terminal and my computer does not respond at all.
