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.
