Vertical lines on the left side Konsole

[ARClite]

There are some various length vertical lines (0, 1, or 2) showing up on the left side of Konsole, appearing after any command like ‘ls’:

I have the same result on a laptop and desktop (garuda-inxi is for the desktop).
I have searched the konsole menu, system settings and KDE forum to no avail. The line also appeared to the left when running inxi. Not sure if this is a feature of some sort, but I haven’t figured out its purpose (if there is one).

Konsole Menu → Settings → Configure Konsole → Profiles → Garuda [Default] → Edit → Scrolling → uncheck Highlighting (Highlight the lines coming into view) → Apply.

[ARClite]

I think this is the correct window:

Am I not seeing something here?

[ARClite]

Ah, found it.

Turned it off. Now it’s down to 1 skinny line.

Change the laptop, it’s also down to 1 line.

When I tried the Built-in profile (the one you can’t edit) the line is gone. But also the nice features too.

[zoeruda]

It’s weird, it does appear like the setting tries to hide those lines by moving them slightly to the left, and apparently not enough. It might be the same as this one 486192 – Grey line artifact on the left side of the screen but not exactly from what I see in the screencast.

Other reports
(Gentoo Forums :: View topic - Vertical blue line on left side of konsole windows,
Bug#985194: konsole: blue bar on the left side when text is scrolling)
seem to have been resolved by turning the setting off, so perhaps a new KDE bug report is needed.

[elite]

its this here

set it to never

[ARClite]

The good news with the ‘Alternating bars: Never’ is that the ‘Scrolling - Highlighting’ selected appears to make the ‘Highlighting the lines coming into view’, work correctly (selected or unselected). But with it selected, it only works on new incoming lines, once you scroll the window the vertical bar will move a bit randomly. So I will leave it unselected. Also I’m not getting 2 bars anymore.

Good to know

i was wondering myself for a while on the test iso. Found it do action too with the mouse wheel but it was okay with other Terminal i didnt looked forward to tweak something
