When SVG lines are rendered in a viewport larger than the browser window on Macs, the lines seem to 
disappear and reappear whenever they feel like it. This problem does not exist on the Windows port.

Reproducible: Always

Steps to Reproduce:
1. Resize Mozilla/Firefox window to a small size. 640x480 works.
2. Got to http://halo43.com/beta/map_view_moz.php?gid=2
3. Click empty space to cause the Javascript to autoscroll the page for you, or scroll manually.
Actual Results:  
The lines appear and disappear randomly.

Expected Results:  
The lines should not be vanishing randomly.

WFM, on windoze
WFM=works for me. (in case anyone wanted to know).

Is this a graphic card issue?

I suggest the reporter take a ScreenShot of the problem.

or

See if it matches this bug, an ATI video card issue -->
https://bugzilla.mozilla.org/show_bug.cgi?id=104992

The 'solution' was to change the screen resolution, or live with it until you
get a newer computer.

I thought I read that some macs were affected as well.

This is not a graphics card issue AFAIK. I tested it with Deer Park Alpha 1 on an iBook G4 as well as a 
Dual G5. One had an ATI card, the other had an nVidia card. Identical problems on both machines.

Again, this only happens on the Mac port. I've never seen it happen in Windows.

I can confirm that this bug still exists in Deer Park Alpha 2, despite "better Mac OS X compatibility."
I have a page rendering well on windows when I use Firefox 1.5 on the Mac (much slower on my Quad G5 compared to slower windows machines) I got the same effect when scrolling the browser window down. It happens with text part of a box (group elements with text hanging under the root of the XML document. I am not using viewport only the browser scoll down.
The start of mine XML document is like this:

<html xmlns="http://www.w3.org/1999/xhtml">

<!-- <body >-->
<body oncontextmenu='return (false) '>
<link href="../../include/contextmenu/contextmenu.css" rel="stylesheet" type="text/css" />

<svg xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink"
     width="99%"
     height="5500"
     onload="init()">

Because of the height of 5500 scrollbars shows up and I can scroll down the diagram.

The software is part of http://open-modeling.sourceforge.net.

I hope you can help Mac users are now not supported by our software.
