on my machine, open a file in emacs, windowmode, navigation around, the curser leafs artefacts on the screen and is than shown incorrect.

would like to make a screen shoot, but when the window loses the focus the view repairs itself.

openSUSE 13.1 KDE, it this some side effect of gtk 3 themes / settings, and how can I fix it
