Hi,
I use GVim ver. 7.3.154 with GTK2 GUI on Slackware 13.37. During page
down/up scrolling with Ctrl-F/B keys, screen flickers. It is
especially well seen when GVim is maximized and working with large
files (for example /var/log/messages) where text fills entire screen
(not only from top to bottom, but also from left to right). Launching
GVim with '-u NONE - U NONE' changes nothing. For additional
comparison I opened the same file with Emacs 23.3.1 and rendering was
very smooth. Of course both editors use exactly the same font. Is
there any chance that GVim will use equally efficient rendering
technique as Emacs? I'm a visually impaired person and this problem
has a great meaning for me. As far as I know Emacs uses libXft to
render fonts. Maybe lack of libXft support in GVim is the core of the
issue?

Try using a more recent version. Vim 7.3.154 dates back from 2011-04-02;
the current patchlevel is 7.3.409. In the 255 fixes between your version
and the current one, some flicker problems have been fixed but I'm not
sure they are exactly what you're seeing. IMHO there's not much risk in
trying anyway.
