gtk.fixed and repaint problems

[rastersoft <raster rastersoft com>]

Hi all:

I'm working with a gkt.fixed canvas because I need to put several 
widgets over an animated picture (created with Cairo).

I created a Cairo canvas that covers the whole window, and over it I put 
the widgets (one of them is an icon list)

With Gtk 2.x and Gtk3 up to 3.6 all worked fine; but with Gtk 3.8 I'm 
having some repaint problems.

In previous versions, it seems that the whole widget is repainted when a 
"draw" event is sent; but with the last GTK, it seems that only the 
modified parts are repainted. This means that, when a "draw" event is 
sent to the window, when I repaint the whole thing, the first element to 
be repainted is the Cairo canvas, so it overpaints all the widgets; 
then, when the widgets are repainted, since only the modified parts are 
repainted, only they are visible, and the other parts are hidden "under" 
the Cairo canvas (when, based on the Z axis, they should be over the 
Cairo canvas).

How can I fix this?

Thanks.
