Jose, Christl: If you load the page in Moz 1.0 or in 1.1 or in IE4+ then the
scrolling text looks as stable as in Moz 1.2beta? Thanks.

I don't see any noticable difference between IE6 and Mozilla 1.2b
I see the same flickering in Phoenix 0.4 as in Mozilla 1.2b .
Must be some interaction between my system (550MHz PIII + 256M mem) and
some recent changes to the Mozilla code.
With build 2002112304 I know see the flicker.

A reduce testcase would be good to have.

Flickers also under Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.2.1)
Gecko/20021130.

Will try to prepare a reduced case.
This bug is weird, now I dont see the flicker anymore. Build 2002120408, Windows
2000.
I posted a reduced case on the site. Start flickering when the 15th character or
so is painted. Flickers with Phoenix 0.4 and Mozilla 1.2.1 . IE 5 SP2 shows it
OK - no flicker. Tested under Win NT SP6a.

The code is as follows:

<html>
<head>
<title>Mozilla Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script LANGUAGE="JavaScript1.2">

var timerId = ""
var doc =""

function startTicker()
{
 	doc = document.getElementById("viewBG")
 	Ticker()
 }
//function to dynamically write text to a layer
function Ticker()
{
objHtml = doc.innerHTML
var len=objHtml.length
	if (len>0)
	     if((len%24)==0)	doc.innerHTML = objHtml+"A<br>"
		else 		doc.innerHTML = objHtml+"A"
	  else doc.innerHTML = objHtml+"A"
if (objHtml.length < 100) timerId= setTimeout ("Ticker()",100)
}
 </script>
 </head>
<body id="body" bgcolor="#000000" text="#000000" onload="startTicker()">
<div id="viewBG" style="BACKGROUND-COLOR: lightgrey; HEIGHT: 100px; LEFT: 156px;
POSITION: absolute; TOP: 140px; VISIBILITY: visible; WIDTH: 470px;
layer-background-color: lightgrey;border: 1px none #000000" ></div>
</body>
</html>

Kob, do you still see this with latest build?
I don't use nightlies or alphas. I will check with Phoenix 0.6 release due in 
January or with Moz 1.3b
Still seeing same flickering with
Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.3b) Gecko/20030210

Reporter: a) Does this still occout with a current Mozilla build?
          b) Have you the testcase avaible on another URL (current is not
avaible), you could also attach one to this bug
Posted the test case on a new server, changed URL to
http://www.padsutilities.com/MozTest/moztest.html

Still flickers with Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.4) Gecko/20030624

I use 550MHz PIII machine (256MB Mem) - does this have anything to do with
the DHTML performance? IE5.5 on this platform shows no flicker.

Kob, can you retry with Mozilla 1.4.1 or 1.5?

With Gecko/20031104 Firebird/0.7+, Windows XP I still see the flicker. Only
sometimes though. Could this be a dupe of bug 170702?

Since this is not WFM, and there is a bug for it, lets then dupe it to it.
