Hi,
I just moved from Windoze to GNU/Linux (Ubuntu 8.10), built emacs
from HEAD with default options. When I open a file, I notice some
lines not rendered. When I scroll up and down, I see the contents. I
have tried the same with vanilla emacs and with my customizations,
they happen in both cases.
I must say that Emacs fonts on GNU/Linux is beautiful (gtk)!

A simple way to reproduce:
1. Run vanilla emacs in window mode on GNU/Linux
2. Open some 'C' file with font-lock enabled
3. Keep pressing C-l repeatedly, you will see lines appearing and
disappearing randomly.

unable to reproduce on my box. Maybe related to your experience, I can
see that since emacs 23 the screen is flickering a lot whenever lines
move, but they are alway properly drawn at the end. Do anybody else see
this also ?
Test box : fairly standard ubuntu, with a radeon and default free
drivers.

C-l is now bound to recenter-top-bottom instead of recenter. Maybe this
is what you're seeing?

I am aware of the recenter functionality, the recenter happens and in
the redisplay, I see some lines or partial lines missing. When I
scroll a screen full which I presume will trigger a redisplay, it gets
redrawn properly to show the complete contents.
I am using Nvdia driver, IBM Thinkpad 61 series with display on an
external lenovo flat LCD monitor. The rest being Ubuntu 8.10 pristine
installation.

The same problem happens on Emacs22 that I installed from Ubuntu
package too. So, this is not something recent. I will try disabling
Nvdia driver FWIW and test again.

The problem was with Nvidia driver #177 which is prompted in Ubuntu
with enough warnings. Once I removed, it just works fine!
Maybe, it could be documented somewhere so that some other user does
not stumble on this issue. Since I knew a bit of emacs and could
realize that it was a display problem. At first, it appeared as if
some data was lost in the file, that can be scary.
