Public bug reported:
This problem only happens to me when I select the Ubuntu WM, not under
Cinnamon. I see it in gnome-terminal.
After I enter a command, like "ls" or "cd" into gnome-terminal and press
Enter, the desktop icons blink out for a split-second, and while they
do, the command does not finish.
This makes it annoying for me to work in the command-line, since I'm
used to most programs responding immediately.
>From my experience, it looks like when a program is already running,
like Vim, and I ask it to do a disk operation, this "blinking out" and
"freezing" does not happen.
I'm attaching a video of this happening.
I've noticed this line in journalctl -b:

The gnome-shell error with .histfile.LOCK stood out to me.
The German means "error fetching information for file
>>/home/agentydragon/.histfile.LOCK<<: file or directory not found".
I had a suspicion that this is some interaction between gnome-shell (and
maybe the desktop-icons extension).
So I just tried disabling the desktop icons extension, and disabling it
removed this "freezing and icons flickering".
I suspect that what might be happening might be some sort of race
between the desktop icons and zsh - maybe like:
- I enter command into zsh
- zsh creates a histfile lockfile in ~
- notification is sent to desktop icons that there's a new file
- meanwhile zsh writes the command into the histfile and gets rid of the
lockfile
- desktop icons get the notification but are unhappy that the file does not
exist anymore
