From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9.6+) Gecko/20011215
BuildID:    2001121508

When I try to scroll the above mentioned web page, I see black garbage 
where the white background should be displayed. This is probably caused
by the 1x1 gif file used as the background:
http://www.est.hu//cgi-bin/matesz/CP/est?MIME=image/gif&FILE=spacer.gif

I'm not sure if it is an actual mozilla bug or an evangelism issue.



Reproducible: Always
Steps to Reproduce:
1. go to http://www.est.hu
2. try to scroll the page using the scrollbar
3.

Actual Results:  Garbage is displayed instead of the white background

Expected Results:  normal white background

I can not reproduce with 2002012203 build on WINXP.

I can still reproduce this on NT4SP6, 256MB of memory, 600Mhz processor with
build 2002012608. Both the webpage, and 
the attached testcase show visual corruption. (the '1x1 Gif..' attachment should
be saved as "est.gif").

It looks like some bug fix fixed this one too. Both the website and the attached
testcase seems to work fine with build 2002022003. So I'm going to mark this
'fixed'.
