A div absolutely positioned to the far right, with a background-image assigned,
that contains the following:
2 main inline elements (<a>'s or <span>'s work)
1 inline element between them
Various CSS rules for these elements, as outlined in "Steps to Reproduce"
will trigger a graphical glitch if you hover over either of the 2 main inline
elements.
Reproducible: Always
Steps to Reproduce:
1. Copy the code below and save as an HTML page. Be sure to check the notes
below the code.
2. Open in Firefox.
3. Hover over "test1" or "test2".
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd"> <<1>>
<html>
<head>
<style type="text/css">
#test {position: absolute; right: 0; padding-left: <<2>>; background:
url(whatever.gif<<3>>) bottom left no-repeat}
b {display: none}
span {padding: 0 7.2px<<4>>}
span:hover {border-bottom-width: 1px}
</style>
</head>
<body>
<div id="test">
<span>test1</span><b>|</b><span>test2</span>
</div>
</body>
</html>
<<1>> XHTML 1.0 Transitional did the same too
<<2>> This should be the pixel width of the background-image. In my case, it
was 32px.
<<3>> I was using an image 32px wide and 9px tall for most of the testing,
although the height didn't seem to matter. Just make a test image in your
favorite graphics program.
<<4>> No idea about this value, but changing it 0.1px up or down makes the
glitch disappear.
Actual Results:
The background image repeated itself behind "test1". This second image
disappears after refreshing, switching to another tab and back, etc.
Expected Results:
Not repeated the background image behind "test1".
Just installed the newest trunk. I first noticed this bug using the 7/25/04
(give or take a day) branch. Still occurs with a new profile. No different
theme. Using WinXP Pro SP1.

I don't know, but from your description it looks like something similar to bug
237766.
Could you attach a testcase, which shows the bug? Thanks.
Hmmm... it may very well be. I don't think your bug showed up when I ran a
search, but maybe I just overlooked it. I'll look at this more tomorrow and
post a testcase if it turns out not to be a duplicate.
I believe my bug is indeed a duplicate. I'm posting some hopefully helpful
stuff to <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=237766">bug
237766</a>.
