Re: gnome canvas doesnt work properly on GTK-DirectFB

["svalbard colaco" <svalbardcolaco gmail com>]

HI all;

Further debugging has shown that *antialiased canvases* formed using
*gnome_canvas_new_aa()
*appear correctly on GTK-DFB backend
whereas canvases formed using  *gnome_canvas_new()* fail to render on
GTK-DirectFB ;rather they appear black instead of white.

Hoping this will give a clearer insight on the said issue..

Any pointers as to why such behaviour is observed could be of great help.

Thanks & Reagrds,
sv.
