This sounds like a bug in the driver/DRI, where it fails to handle
composite correctly. At a guess, you have the compositor enabled in Xfce
and disabled in KDE, and this is causing your problem. (Alternatively,
it could be that Xfce uses the compositor differently.) Either way, the
bug lies in the driver, not Xfce.
