Public bug reported:
To recreate:
* I'm running Ubuntu Server 16.04.1 LTS (no GUI).
* I'm using byobu `5.106-0ubuntu1`.
* I press F1, then enable the "disk_io" notification, then choose "Apply".
* While doing nothing at the command prompt, I watch the status line.
What I expected to happen:
* I expected Byobu disk_io report to fluctuate in obvious (or at least
believable) ways corresponding to my activity on the system.
What I found to happen:
* Byobu's reports of disk_io did not correspond to the commands I was
typing, nor reports from `iotop`.
Notes:
* I am using a freshly installed system.
* I don't have many other processing running. I installed PostgreSQL, OpenSSH,
and basic development tools.
For example, typing `dd -h` results in "<-72kB/s" (disk reading)
remaining on the status bar for an extended period. I've waited for what
seems to be several minutes but the status is not cleared.
I would be quite surprised if that exact amount of disk IO is happening
for an extended period.
I ran `iotop` to see what processes might be causing an ongoing disk
activity. Nothing seemed to correspond.
Theory / Possible Explanation:
* It would appear that when disk activity changes from a non-zero value to
zero, the previous value is not cleared out.
* This could be a simple matter of the TUI (text user interface) having a stale
output, perhaps due to a rendering bug.
** Affects: byobu (Ubuntu)
Importance: Undecided
Status: New
** Description changed:

What I expected to happen:
- * I expected Byobu to report intermittent, fluctuation disk activity
- that corresponds to my activity on the system.
+ * I expected Byobu disk_io report to fluctuate in obvious (or at least
+ believable) ways corresponding to my activity on the system.
What I found to happen:
* Byobu's reports of disk_io did not correspond to the commands I was
typing, nor reports from `iotop`.
Here are two examples:
* Example 1: On my system, "->372kB/s" (disk writing) remains on the
status bar for an extended period.
My system is freshly installed, so I would be quite surprised if that
exact amount of disk IO is happening for an extended period.
* Example 2: On my system, "<-912kB/s" (disk reading) remains on the
status bar for an extended period.
I ran `iotop` to see what processes might be causing an ongoing disk
activity. Nothing seemed to correspond.
