I noticed my Macbook was getting hot, checked CPU usage, even before starting the print, when the GF “Ready to print” dialog is up, Chrome Helper is using >300% CPU. It stays that way while the app is “in focus” but not when flipping to a different tab.
Thanks for getting back to us with these! I’ve passed your details on to the team. We’re looking into it now. I apologize that I don’t have more information right now, but I’ll update this thread when I do.
