Horizontal line screenshot

From some time (probably since 19.04.0) a horizontal line strike through my tabbar in konsole. It is good visible only in Oxygen theme. In Fusion and MS Windows there is something but above tabs. In Breeze everything looks OK.

It can be Oxygen problem, but I don't observe this kind of problem in other KDE apps.

OBSERVED RESULT
Line above tabs.

EXPECTED RESULT
No line above tabs.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Slackware current with Alien plasma packages.

Just in Konsole, or in other apps too?
Comment 2 Konrad Rzepecki 2019-07-24 04:15:55 UTC 
I see it only in konsole. But i didn't check every app.
Comment 3 Konrad Rzepecki 2019-07-30 11:25:47 UTC 
I found something out. This line comes from "new tab" button. Without it, disappears. It is also visible when tabs are at the bottom. This time below icon, and almost match tab bottom boundary line, so is less visible.

Similar line appear when close tab button is added besides tab, however this time line hide below tabs (is visible only above button).

In every of this cases, this buttons seems to not be separated properly from tabs.

And, I'm not convinced that this is oxygen issue...

Minimal working example
Comment 6 Mariusz Glebocki 2019-08-02 16:22:42 UTC 
The bug is caused by CSS used for removing 1px margin in Konsole: "QTabWidget::tab-bar, QTabWidget::pane { margin: 0; }".
The line is drawn even in Breeze, but it is placed below tabs and is hidden by terminal.

Moving back to Konsole.

Note the Qt docs for https://doc.qt.io/qt-5/qwidget.html#styleSheet-prop have a warning:

Warning: Qt style sheets are currently not supported for custom QStyle subclasses. We plan to address this in some future release.
