dstat is very nice and I am using it more and more. Thanks for
maintaining it within Debian.
in my case weirdness came:

that layout started to break when I started a new task (some CPU but
primarily IO/disk bound due to traversal of the filesystem):
$> grep . */*/SHA* |pigz -9 >| grep-all-SHAs.txt.gz
according to top it is the bash process which is the busiest indeed:
