I can confirm that window resizing looks much better now, I don't see
the annoying flickering anymore, thanks a lot !

Not related to your patch but annoying, I would say that repainting is
kind of slow compared to gtk. When resizing a GWorkspace window to a
bigger size (in the icon view for example), the old content is repeated
in the added area before drawing completes and displays the new content.
Do you also see this ? With today's computing power I find this strange.
