gdk_window_move error in DirectFB

[?? <hui003.zhang@xxxxxxxxxxx>]

Hello, everyone,

         When I adapted Gtk+-2.10.1 in DirectFB, I found the menu scroll couldn’t proceed, and the error of SIGSEGV was reported in what _cairo_pixman_composite_solid_mask_nx8x8888mmx in fbmmx.c.

         At last I fount it was brought in by the call to gdk_window_move in function gtk_menu_scroll_to, if I substituted it with gdk_window_move_region, no error was reported, but the show result was not correct.

         Getting deeper, I found once the menu item in the bin_window was moved outside the father gdkwindow ------ view_window, error would come.

         As a test, I drew an arrow in the bin_window, similarly, error emerged when the arrow was move outside view_window along with bin_window.

         I have posted this on gtk-list@xxxxxxxxx, but no response came. Maybe there are some knowers.

         Thanks in advance.
