I don't remember, that any rendering issues have been fixed since the
release of 7.3 Try if scrolling using <C-E>/<C-U> works better, e.g.
fu! Scroll(up)
return ":\<C-U>exe \":norm! ". v:count1*winheight(0) . (a:up ?
'\<C-U>' : '\<C-E>')."\"\n"
endfu
nunmap <C-F>
nunmap <C-D>
nnoremap <expr> <C-F> Scroll(0)
nnoremap <expr> <C-D> Scroll(1)
