I posted a reply earlier in which I recalled vaguely that Chromium may
be the Lubuntu default browser because Firefox is more memory-hungry.
Be that as it may, Firefox runs nicely on the LTSP client and is not
subject to this choppy scrolling problem. So the bug report comment
that Jakob found seems to have hit this problem squarely.
I had toyed with the thought of installing Chromium as a local app to
address the problem, but doubted that it would run well on minimal-spec
clients. Nonetheless, Richard Doyle also logically-enough urged an
attempt in that direction. And since I could find no published hardware
requirements for Chromium, I decided to dive into those newbie waters
and try to test it as a local app.
I succeeded in getting Chromium installed as a local app, but found that
it took a stunningly long time to launch, so that disqualified that
potential solution.
There is a second part to the attempt, however, since Internet apps
won't work as local apps on a two-network-interfaces server unless you
set up the LTSP server as a NAT gateway. (The LTSP clients will lack
name resolution services until that's set up.) I have not yet succeeded
in getting that working, and since I do want to learn how to do local
apps but it's now off-topic here, I am pursuing that in a separate
thread with topic: "Getting NAT working for Internet Local Apps under LTSP."
Unless I discover that Firefox causes some annoyance on the client that
is greater than the Chromium scrolling problem, I confirm that Firefox
is currently the way to go on the LTSP clients.

With fully updated Lubuntu 12.04 on a server with an AMD 3400+ and

scrolling in Chromium 18 on the terminal is choppy.
The same result on a terminal with Celeron 500 MHz and 196MB.
This is the case even with mostly text content, like a page of Google
results.
Scrolling on the server is very smooth.
This is a test setup with just one server and client, nothing open on
the server, and a 100 Mbps connection.
Anyone know why and if I can fix it?
Yes, I have also noticed that.
There is a bugreport,
http://code.google.com/p/chromium/issues/detail?id=28544 , quoting:
Comment 25 by e...@chromium.org , Jan 26, 2010
Chrome has a different drawing model than other browsers (due to the sandbox,
web
pages render as images). It means that it is unlikely to ever perform as well
over
remote X as other browsers.
So basically, you'd rather use Firefox on LTSP.
