CPU core maxed out until I open a menu in the editor (context, dropdown, etc)

Not sure what is up with this, but one of my CPU cores remains pegged, and a second stays at about 50% at pretty much all times unless I open a menu somewhere in the editor. I tried it out with different windows open and different menus, but it remains maxed out until any menu items is opened.

Is this just something I need to get used to? I worry about the longevity of a core being completely maxed out at all times no matter what else I am doing if Unity is open, as it is pretty much open all the time when I am at my pc.

Probably a bug. Guessing that one of Unity's root level windows is doing a constant loop until you're hitting a dropdown. You should report a bug!

Though, try to revert the layout to default first. There's so many bugs that are fixed by that.

 

I gave that a try, reverting layout and restarting the editor, unfortunately, there was no change so I will go ahead and do a bug report.
