change adwaita theme border width

[arapaho]

Maybe a better fit for kde is adwaita-qt.

No, if this is for qt apps only qt apps will use it. Gtk apps will use gtk themes even when they are used within Plasma KDE environment.

The solution to my problem need to be solved by editing gtk2 theme and changing the frame of the scrollbar slider. But I can't find good guidelines.

Possibly the Kubuntu forum could help in this. Not running your environment puts me at a disadvantage.

Well I dug out my $20 laptop, it runs Lubuntu 16.04 and gtk2.

Both adwaita and clearlooks-phenix v7 test ok.

@arapaho
Have you tried changing your kde theme and see if it has any effect on adwaita?

Thank you for testing. The problem is with stardict 3.01. I tested on xfce and with other themes and on all of them the problem exist. With other programs like libreoffice, firefox I don't have this problem. I sent an email to stardict developers and I will wait for answer.
