Screen shot of renderig errors in Midori

Webkit 535.4, GTK Version mis-renders UI widgets.  Especially apparent on drop-down selector boxes and text input fields.

Web pages exhibiting this behavior include one or more of the UI widgets in question.  Behavior is especially apparent during rapid up-down scrolling.  The UI widgets seem to render in the wrong area, usually collecting on the left side of the display.  Sometimes the upper left side.

Sometimes by slowly scrolling down and then back up again, the mis-rendering goes away.  It's very unpredictable.

Other Information
-----------------
- Both Midori and Gtklauncher (simple web browser) exhibit this behavior.  They are both using the same version 1.6.3 of libwebkitgtk-1.0
- Gnome/Epiphany browser on the same platform does *not* exhibit this behavior.  It uses uses libwebkitgtk-3.0.
- Don't know if this is relevant, but the X session was being viewed using a remote X session (over NX / x2go / ssh)
