Gtk textview issue with scrollbar (gtk2.14.7+directfb1.3)

["Wang, Pengzhuo" <Pengzhuo Wang windriver com>]

Hi all,
  I'm running gtk-demo (gtk2.14.7+DirectFB 1.3), and found  textview
backgound color turn into black color,instead of orginial white color
when scrolling bar. 
After that I  can see the text content of textview only by clicking the
area of textview.
 Did anybody meet such issue before? Any good suggestion? Thank you in
advance.

Best Regards
