"For your Clean install, what did you use for the migration data source, Time Machine, or CCC?"
I used a CCC image copy. One thing that was necessary after that was to Repair Permissions - they seemed to be a bit of a mess, but after doing that, things ran a lot more smoothly.
By "clean install", do you mean that you completely erased your internal HD, installed the OS,set up a new Mac user account, re-installed all applications and utilities from their original DVDs etc, re-entered all your email accounts, and then copied across documents, images, movies, or did you use Migration Assistant to do all the above for you?
I ask because I used to do the above erase and clean install to avoid gitches being carried over but it is a very time-consuming process. I'm not sure that it succeeded in removing the glitches but if it did in your case, I might try it for OS 10.10.x
