I have a recurring problem that some Commands have a big lag when being displayed in the command column.
Sometimes it’s possible to perform other operations during that time, sometimes not.
This video shows how I want to drag a small jpg that is placed with a “picture frame”.
The scene contains nothing else apart from the donut and the pipe below it.
I’m unable to reproduce this on my machine (MBP, macOS High Sierra 10.13.3, Rhino 5.4)

I would be curious to see if you get different performance when you boot macOS to Safe Mode. You have a number of third-party kernel extensions loaded. Booting to Safe Mode will not load those extensions. It would be good to rule those out.
