My theory is that you dont see this issue with on polygon filled with solid color because the resample strategy find the same color in all the considered portion of polygon.<br>
This is not true for labels or lines.</p>

<span>When I use mapserver wms to serve the raster tiles from the file system, they look fine. But doing it from the database gives me problems with the black labels as can be seen by the image at <a href="http://phased.co.uk/wp-content/uploads/Screen-Shot-2014-08-20-at-15.49.09.png" target="_blank">http://phased.co.uk/wp-content/uploads/Screen-Shot-2014-08-20-at-15.49.09.png</a></span></div>
