Actually it does, I didn't see the correct reason for double buffering not
working. It turns out that since the container widget Emacs uses isn't double
buffered, all the children (scroll bars) does not get double buffering either.
I have checked in a fix for this (actually a couple a days ago, but it was
incomplete), hopefully it finally fixes this problem (hey, one can hope :-).
