However, I have no problem with Google Mercator. <br>

Would really like to know how to fix this!<br>

<div class="moz-cite-prefix">I can verify this same behavior on
Win7 with QGIS 2.4 64b. I think it has to do with the shapes
crossing the 180º line. If you zoom in to a smaller area that
includes only countries in one hemisphere, the borders look OK.
Also, it's not only Robinson and Mollweide: any global
projection will show strange trapezoids (even "Google" mercator)<br>
I also see that if you use the *spatialite database file* from
naturalearthdata.org this problem disappears. You can switch to
other world projections with no problem.<br>

Hi all,<br>
<br>
I'm using the KyngChaos install of QGIS on the Mac (Mavericks
and Lion, on different machines), and I've been having
problems with projections including Robinson and Mollweide
from QGIS 2.2 onwards.<br>
<br>
Everything was fine in QGIS 2.0, but in 2.2 and 2.4,
re-projecting a world Natural Earth shapefile to a Robinson
projection, for example, gives this:<br>
<br>
Any idea what might be going on, and how to fix it?<br>
<br>
Thanks,<br>
<br>
