Hello everyone.

I use Debian Wheezy with KDE 4.8.4. A couple of days ago I noticed that Dolphin is not displaying arrows in details view mode. Also 'places' panel has different background color than it should. Here is the picture so you can see what I mean.

It stays the same when I change color theme, icon set, widget style and desktop theme (panel look changes back to normal if i change widget style).
Also notice the disk usage bar is weird, even if I change widget style.

But if I log in as a different user, everything is ok.
So it looks like my user configuration is messed up somewhere.

What could be the cause of this problem and how could I solve it? Thanks

Which widget style are you using?

If it is Oxygen, have you tried changing the preferences at System Settings > Application Appearance > Style > (Configure) > Views?
You probably want to check "Draw tree branch lines", and select "Small" or "Normal" as the triangle size if you use that option.
