From Bugzilla Helper:

BuildID:    2000121804

I've noticed this problem on  When you scroll a bullet list
with the slide bar, some bullets generates a lower right diagonal line, most of
the time to the next text line, sometimes longer than this.  ALT-TABbing from a
window to another cause refresh and solve the glitch.  This appends only when
scrolling up.

Reproducible: Always
Steps to Reproduce:
Load the testcase file I included.
Scroll the page with the scrollbar to the bottom and then scroll up slowly.
Notice the glitch.

Actual Results:  bullets generates diag lines to lower right		

Expected Results:  Only bullets, no lines

Reporter, what video card and driver are you using?  I've seen this bug before,
a long time ago, and it was fixed with a newer display driver for me.

I'm using Win ME, Diamond Viper 2 card with lastest driver found on Diamond's 
site, and Direct X 8.0

Reporter, sad to say, this is a Viper 2 driver bug.  I should know, as I work at
S3, and I'm the one who originally reported the bug to get it fixed here.  Get
the latest reference driver (should be higher than v9.51.06, if I recall, for
the fix) from the site, and it *should* fix this problem.
It's certainly gone for me.  Someone should close this bug, too.  I'm not sure
how to change the status.

I only found v9.51.03 on  Anyway, let's not loose time on this 
one since it's a known driver issue.  But I'm still wondering why this problem 
occurs only with Mozilla, and not with IE5 and NS4.7x?

Good call, since I can't see this with 122920!  I guess that another fix fixed
this one too.
