The colours on the chat-ui window scrollbar doesnt match up with the colours above and below it (while the contact list one does) I'm not entirely sure if this is a Qt oxygen theme styling problem, or if it's a Ktp text-ui problem, so apologies if this is reported to the wrong place. Reproducible: Always
The scrollbar is actually theme-dependent, but not all the themes define it. The one in the picture is the default one. I don't know where it comes from, but it could be a problem in webkit
Easy to test, open Rekonq and have a look.
In rekonq, the top looks ok, but the bottom doesn't.
Given this happens when I drag a QWebView into QtDesigner and run preview, it's clearly a bug in either Qt or oxygen. I don't think we can do a lot about it here.
