Hello,<br>
<br>
The following components are used:<br>
- CartoCSS: <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="https://github.com/egore/openstreetmap-carto">https://github.com/egore/openstreetmap-carto</a>
with defaults scale=1 and metatile=2<br>

That repo is significantly behind openstreetmap-carto, and
improvements have been made to road shields since then.<br>
<br>
Additionally, 2x2 meta-tiles are very small for production use and
will lead to more labeling problems. 8x8 is standard, but even 4x4
will be better.<br>

What buffer do you have set? That's probably the most significant
setting, assuming the style is not clipping the linestrings for
shields.<br>

And now we have at different locations some strange shifts. Look
at the shields.<br>

Can someone explain why this can happen? With Mapnik as a real
Mapserver and single tile no problems (of course). <br>
<br>
Mayby someone with a solution?<br>

It is inherently impossible to avoid all meta-tile label placement
problems unless refusing to place labels on MT boundariesaltogether.<br>
