refresh bug in the canvas

[Bruno Coudoin <bruno coudoin free fr>]

I am the author of gcompris and I suffer badly from a refresh bug in the
canvas.
http://bugzilla.gnome.org/show_bug.cgi?id=91583
I checked the CVS today and it's still there.

The easiest way to show evidence of the bug is the fifteen game demo in
libgnomecanvas/demos/canvas_demo the pieces are not refreshed after the
move (you move the window out of the desktop area and bring it back and
you see the moved items)

We added a bunch of gnome_canvas_update in gcompris as a workaround and
it's better now.

I don't know if gcompris is the only app to suffer this but my users are
disapointed :(

Do you know if somebody familiar with the libgnomecanvas code is aware
or working on this ? If not, where should I look ?

Bruno.
