Consumes 30%+ CPU while doing absolutely nothing
I have a Nautilus window with two tabs opened, at folders that just contain a handful of files and subfolders each (even if they contained millions of them, that wouldn't be a reason to justify high CPU consumption while idle, but that is not even the case).
Whenever I give focus to the Nautilus window, even if I do NOTHING in it, it starts consuming about 30% or more (sometimes even with peaks over 60%) for a whole few seconds. Doing trivial stuff such as switching tabs also causes peaks of CPU consumption for a few seconds.
