Same. I have 10 CGPDFService processes running for over 24 hours. Two CPU's are at 100%, and together they're using 15GB of RAM. I can SIGKILL but they come back after 5 minutes. Some people believe they're related to the slow-mo screensaver, which I disabled in my settings. It's only happening on my Mac Studio (which isn't logged in), and not on my Macbook Air (which I'm currently using).
