Hello
I just installed a new Debian distribution with KDE plasma.
In "System configuration" (systemsettings5) -> Appearance -> Appearance of applications -> Graphic component style
There's always a "Configure" button.
This button always has a "Scroll Bars" tab.
But there is no longer the possibility to adjust their width.
Having a very high resolution screen (125 dpi), these bars are only a few pixels and are difficult for me to reach.

With the previous version under Kubuntu 16.04, I could set the width to 15 px.
There's always a "Configure" button.
This button always has a "Scroll Bars" tab.
But there is no longer the possibility to adjust their width.

How do I reach this setting?
Thank you for your possible answers

Can you please give us your systems version, KDE version, and plasma version please?
For instance, I am using Plasma 5.18LTS on kubuntu 20.04, and I cannot find the same setting menu you are referring to.
From one version to another it might change.
On this 5.18 for example, the scaling has been relocated to the Display options, since it scales the entire desktop to your like.
Cheers

I have installed Debian 10 Buster distribution with KDE plasma version 5.54.0.
On my older versions of KDE plasma version 4.13.3 and 5.12.9, there is the possibility to adjust the width of the scroll bar.

That is the Frameworks version, not the Plasma version, please check the System information in the System Settings or with KInfoCenter

Sorry,
Plama version is 5.14.5
