Hi It is driving me mad what Spell Book is doing. The whole Dock bar is constantly shaking. The window (of any application) that is active at any given time switches to whatever window it is.
It looks as if Spell Book is starting up and closing a dozen times a second.
Here is a gif of what is happening and that it is Spell Book. https://share.cleanshot.com/Tz9RyLSN
