Artifacts in title bar

I'm using 13.1 and KDE 4.11.5. I'm also using Chrome Beta. That is where the problem is worst. If I move between tabs, the previous title does not disappear. It grays out and remains. Often, the title bar will show the entire url of the page I am on and it remains, grayed out, when I move to another tab. I notice this in Konsole if I have tabs open and move between the Konsole tabs.

If I move from one application to another or to the desktop and back, the title bar redraws and the artifacts disappear. Obviously, this is not an earth shaking problem. But, if anyone knows of a fix, please share.
