gnome canvas doesnt work properly on GTK-DirectFB



Hi all

Built a gnome canvas application on GTK-DirectFB(gtk+-2.10.14) and certain portions of the windows appear black ,
On clicking in the windows some of them appear white as expected.
What could be the reason for such a behaviour on GTK-DirectFB backend.?

Investigation has revealed the following: (please correct me if i'm wrong)
- since cairo package is built w/0 X linkage , there is an issue with  cairo_draw_with_xlib
and hence the canvas is failing to render.
-The gtk_widget_send_expose ( ) must be replaced with gdk_window_invalidate_region( )
in certain portions of the code.
-Upgrading the cuurent cairo (orignal was 15.4) version didnt help.
-Could it be a gtk d version issue ?

Dont have a clear understanding in this regard , any inputs/cooments  on the sited issue
will be of great help.

Thanks & Reagards
