strange blue lines in gtk-apps

[Peter Schmidt <netzinfos arcor de>]

Hi,

does anybody have blue lines in programs like sylpheed-claws? I have
them in xmms if I want to open an audiofile with the"eject"-button. But,
GIMP itself does not show those lines.

Please take a look at a screenshot here:

Is there a solution out there?

I use Mandrakelinux 10.1 Official.

Here's a list of the installed gtk and gnome packages.
