<pre>Created <span class=""><a href="attachment.cgi?id=273543" name="attach_273543" title="Sample test case">attachment 273543</a> <a href="attachment.cgi?id=273543&action=edit" title="Sample test case">[details]</a></span>
Sample test case
See attached test case. The first example has:
<div class="container">
<div class="particle" style="filter:blur(10px)"></div>
</div>
particle is fixed 80x80, the container is 100x100. The 10px blur should make the particle 100x100 large, but the compositing layer (see web inspector) shows a 136x136 layer.
For example 2, the blur on the container should be 120x120, but it's 156x156 instead.
It's strange in example 3 that the layer is 100x100, but the blur extends past.
I think example 4 is correct?</pre>
