I use Lubuntu and I am very content. Some days ago I was playing around and installed KDE. I removed it a couple of hours later. After that I noticed that the notification boxes that Lubuntu was showing (like those from Pidgin) were no longer black with white bold text, but light gray with white normal text. I can barely read what they say when they pop up.
Some settings might be wrong somewhere. Can somebody point them out?
Here's a small screenshot.
