See the URL for an example.  In this example,
I entered the text:

  "note the junk left by the cursor"

and moved the cursor back a few words using the
arrow keys.

Sorry, I thought the required information was
deduced automatically from the HTTP requests:

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.8) Gecko/20020204

Hmmmm, I don't see this at all in my Mozilla 03/06/02 Linux DEBUG build.
Reporter, have you tried a recent nightly build?

Just tried Build 2002030708 -- still broken.

However, I also noticed that it's only broken
on my Slackware 8.0 box.  I also have machines
running RedHat 7.1 and 7.2, and it works on
both of those.  (I didn't notice this before,
because I usually run Mozilla on the Slackware
box, and it's been broken for so long that I
had almost gotten used to it.)

I'll do some extensive testing and post an
update on this later.

Looks like the bug is caused by the NVIDIA driver included with
XFree86 4.1.0.  When I use the fbdev driver instead of the nv
driver (in XF86Config), the drawing errors are gone.

So can we close this as INVALID?

Comment 8

[Haakon Riiser]

I have not looked at the code in question, so I don't think I'm
qualified to make that decision.
 
But there's one thing I'd like to ask before you make it INVALID:
Is it possible that this could be caused by assumptions in your
code that fail on certain display drivers?  (I'm asking because
the driver only causes problems in Mozilla.)

Comment 9

[Haakon Riiser]

I think we can close this bug as INVALID.  I just installed the
latest drivers from nvidia.com (NVIDIA_GLX-1.0-2802 and
NVIDIA_kernel-1.0-2802), and now it works again.  Must be some
obscure bug in the version included with XFree86 4.1.0.
