You mean 'G' command ?
I write a single script to get quickfix autoscroll, problem seems have been
solved
by 'normal G' with 'windo'.but the cursor seems a little strange:
1. blinks in a strange frequency: sometimes fast and sometimes slow
2. 'moving cursor to quickfix window and back' is noticeable, especially in gvim
3. sometimes cursor moves to ex-command area and stays 1 second and returns to
the previous window
version: 7.4.1902
quickfix_autoscroll.vim
--------------
" scroll down
function! Quickfix_Scroll()
if getbufvar('%', '&buftype') == 'quickfix'
normal G
endif
endfunc
" find quickfix window and scroll to the bottom then return last window
function! Quickfix_AutoScroll()
let l:winnr = winnr()
windo call Quickfix_Scroll()
exec ''.l:winnr.'wincmd w'
endfunc
" timer callback: simulate a long-time-running job
function! Callback(id)
if !exists('s:index')
let s:index = 0
else
let s:index = s:index + 1
endif
caddexpr "output ".s:index
call Quickfix_AutoScroll()
endfunc
let s:index = 0
let s:id = timer_start(1000, 'Callback', {'repeat':30})
cexpr ""
copen 5
wincmd k
--------------------
Quickfix seems to be designed for the old synchronizing usage (make/grep)
But after job/channel have been implemented, quickfix should be widely used to
display
realtime output of the background process .
When background process takes a long time (eg. rebuilding vim source code),
autoscroll
enables me to watch the building progress and the output while I am editing /
navigating the source files
just like what I do in visual studio.
Auto scroll can be simulated by using the script above, but is this a
appropriate way ? (cursor problem, etc)
Is it possible to do this in a more graceful/easier method ?

You can use
:copen
$
{jump back to original window}
Note that recent changes were made to avoid updating the screen each
time, because it was slow. These commands will make it slow again.
You could use a timer to postpone the scrolling or only update once in
so many times.
