Noticed that linux mint was getting a bit laggy. nemo-desktop process was going at full blast. Turns out my laptop CPU was choking in some battery saving mode and plugging power back in fixed it.
Except it didn't. nemo-desktop was still a bit of a hog.
Maybe it was doing some background maintenance. But I looked around and someone suggested moving desktop icons into folders so I did that and now it's at 0% CPU.
As a dev I'm like wut? Desktop runs in immediate mode updating rather retain mode?
