After installing macOS Sierra 10.12, I have started seeing these ghost windows across the top of the screen. Unfortunately they are appearing at random and I can not determine if this is the OS, a specific application, or a general bug of some kind.
Has anyone else come across this and a way to fix it without rebooting your Mac?

Plan of Attack
- Next time is occurs I am planning on running through all of these commands.
