scrollbar corruption

[Michael Schwendt]

KDE with FC3 RC5

Attached image shows what I see in e.g. Firefox, Mozilla, gqview.  The
bottom line of the draggable area of a vertical scrollbar is corrupted
and filled with garbage when I move the mouse over it.  The garbage
varies with time, almost like a structure in memory is copied. It's
fully reproducible.
