On a slighty unrelated note, I was actually wondering about this. 
Shouldn't GTK set BackingStore to WhenMapped in all windows these days? 
Besides the swapping that Alan is mentioning, it would also prevent the
ugliness that happens when applications are not redrawing themselves
because they are busy doing something.

Of course this is assuming that the X servers honors the setting, which
is not always the case (but maybe that can be changed too, at least for
local displays?)...
