1.) My screensaver would take a long time to disable after hitting a key.
2.) Usually errors like below will follow.
3.) Compiz sometimes uses 100% or high CPU
4.) My window controls will disable (eg. the minimize, maximize and close buttons).
It seems like Compiz or appearance/effects disable themselves.  Re-enabling Desktop Effects under Appearance temporarily fixes it.
5.) high load in general from things like "Migration" processes.
