note the odd tail on the 'e' when width="150" on the foreignObject
User-Agent: Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9.1b1) Gecko/20081007 Firefox/3.1b1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9.1b1) Gecko/20081007 Firefox/3.1b1
I was testing filter effects on foreignObject elements, and I found that if the filterRes and the foreignObject sizes hit certain combinations, the text in my foreign html would appear corrupted. The corruption is sometimes a vertical stretch, but sometimes stranger, like another tail on a letter.
Reproducible: Always
Steps to Reproduce:
<?xml version="1.0" standalone="yes"?>
<svg xmlns = "http://www.w3.org/2000/svg">
<defs>
<filter id="filter" filterRes="500" x="0" y="0">
<feGaussianBlur stdDeviation="1"/>
</filter>
</defs>
<foreignObject y="130" width="150" height="500" filter="url(#filter)">
<body xmlns="http://www.w3.org/1999/xhtml">
<div>a b c d e f g h i j k l m n o p q r s t u v w x y z</div>
</body>
</foreignObject>
</svg>

Can you provide the testcase as an attachment like you did with the screenshot rather than just pasting it into bugzilla inline please?

Looks OK to me with the latest trunk. You can get one from here:
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/
If you use that, do you still see the issue?

It's a lot better, but some widths still have artifacts. My new example shows a funny tail below the 'y' at width=202

Here's the screenshot. Note the junk under the 'y' when the foreignObject width=202.
This is ubuntu 8.04.1, pango 1.20.5-0ubuntu1, cairo 1.6.0-0ubuntu2. From xdpyinfo:
X.Org version: 1.4.0.90
dimensions: 1440x900 pixels (373x231 millimeters)
