<p>Hello!</p>
<p>Yes, cairo does some anti-aliasing per default, though I am not
aware of any behaviour changes. <br>
</p>
<p>Can you set up a simple test-case that reproduces the problem?</p>
<p>To me it simply looks like some device-scaling and coordinates on
half-points. <br>

<br>
<br>
I'm trying to debug test failures in the WeasyPrint test suite
(which uses cairo under the hood). The tests started to fail in
Fedora rawhide around the same time as cairo 1.17.4 was added to
Fedora.
<br>
<br>
I attached an example rendering:
<br>
- table_vertical_align.png is the actual rendering with cairo
1.17.4
<br>
- table_vertical_align.expected.png is the rendering in cairo
1.16.
<br>
<br>
My question is: Does anyone have an idea what could cause these
rendering changes? Is there some new antialiasing setting enabled
by default?
<br>
<br>
Please note that I'm not 100% sure that the cairo update is
actually the root cause but I got confirmation that others seeing
these failures as well.
<br>
<br>
Thank you very much,
<br>
Felix
