Bug#1074073: systemctl: some lines flash for no apparent reason

[Michael Gold]

Package: systemd
Version: 256.1-1
Severity: minor

Dear Maintainer,

When I run systemctl, some lines are under-lined; and since some time
within the last year, these have flashed at about 1 Hz. It's annoying
and makes them difficult to read.

For example, these lines are affected:
proc-sys-fs-binfmt_misc.automount
user.slice

I'm using urxvt, but xterm and mlterm behave the same way.

The under-lining seems non-sensical, although the manual explains it:
The header and the last unit of a given type are underlined

I find no mention of what the flashing is meant to indicate. If it's
intentional, it should be explained and there should be some way way to
disable it.

- Michael

There are no patches affecting this downstream. Issues unrelated to
configuration/packages/patches need to be reported upstream. There's
already a github issue about this.
