Mozilla is renderin garbage in the end of the page:
http://gvt.net.br/index_ie.jsp

To reproduce the bug, load the page and keep scrolling to the end. Each
scrolling will alter the end of the page with garbage.

Could reproduce the bug on win98-Mozilla_rc3 and linux-Mozilla_rc2. Works fine
on winXP-Mozilla_rc3.

build: 20020530 12 (Moz 1.0, Win98)

ah yes.
Exact same problem happening with me, for quite some time now, actually.

Reporter: Do you by any chance have an nVidia GeForce2 MX200 / 400 ?

If so, it's most likely a problem with the drivers, as I've found.
I even installed the latest ones, but didn't help.

Notive however, problem doesn't occur with the pgdown / pgUp keys. But only with
the arrow keys, mouse wheel, or the scroll bar.

marking new for time being.

also a point to note:
this is with a new profile (old deleted), new reg entries, and with a clean
unzip / install (NOT over the older build).

humm, is this a dup of bug 75214?

which is supposed to be about rendering garbage, but they seem to be talking
about the page being cut-off at the bottom, or something.

the summary clearly states this problem.

Waheed, I don't think it is a problem with an specific video driver. I tested on
3 win98 machines (SiS 550, Matrox Millenium and I have no idea what the video
card on the laptop was) and the bug happens on all of them and also on a linux
box (red hat 7.2) with a Diamond Stealth.

I can't tell if it is a dup of bug 75214. The url from that bug renders some
garbage while loading the page, but after completion the page is fine for me.

ah, my other two computers have a Matrox and an ATI Rage Pro, and this bug
occurs on both. But Roger, you're probably right, it probably doesn't have
anything to do with graphic cards.

my suggestion for fix (obvious):
have a white background by default.
because it looks like it is the graphics card memory that is somehow being
displayed in a graphical form.
...
humm, actually, I just changed the res/html.css and res/quirk.css file so that
background is always white, didn't work.

(almost?) the same problem used to occur on the background (gray part of) print
preview, when scrolling.

this might help to fix this bug:
bug 117072

Marc Attinasi: could you please quickly look into this, if it may help?

Yeah, it also WFM now. I think they updated the site though...
