Can you post a screenshot? I run Konsole with a dark color scheme and the inline scrollbar looks fine to me.

Comment 3 Bruce Dubbs 2019-02-22 23:04:18 UTC

Just to be clear, this system is a linuxfromscratch build.  I did try to look at the konsole source and can hard code a change to the scrollbar, but I can't figure out how to change the color of the 'thumb/slider'  I can change the outline of the thumb, but it is only one pixel wide and very faint.

Could this be a qt-5.12.1 issue?

What widget theme are you using? Looks like it's not Breeze.

Comment 5 Bruce Dubbs 2019-02-22 23:20:29 UTC

My window manager is xfce.  I have tried many different themes including Adwaita, Clearlooks, High Contrast, Mist, Redmond, Xfce, etc.  None changed the scrollbar appearance in any way.

I've made a little progress.  I brought up plasma and the konsole scrollbar visibility is fine there.  If I go to another system and log in via ssh on an xfce based system, the scrollbar is as as I described earlier.  

This is different from earlier behavior.  I went back and checked and the versions that were OK were konsole-17.12.0; kf5-5.41; qt-5.10.0.

Do you support konsole in a non-plasma desktop environment?

Yes, though not as well as we should, clearly. :)
