Suse 9.0/KDE 3.2 issue

Hi, I have been using the mentioned combo with no problems on my ThinkPad 600X, except for one issue. There are vertical lines in applications. For instance, the Shell/Konsole has lines about 1/2 inch apart in the toolbar area and then several lines in the text area. Also in Konqueror, throughout most of the page. The background is fine, but I guess that's just a single image file. I thought it was a resolution issue, but it seems not to be. The res is set to 1024X768 at 24 bits. Any help would be appreciated....Michael
