<div>Yes, on my system the problem also resolves on
zooming - although I'd only use Robinson for a
global view.<br>
<br>
However, I have no problem with Google Mercator. <br>

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

<div>Try turning off 'Simplify geometry' for the layer (in
layer properties) [0]. For new projects, not existing
ones, the default behavior in QGIS 2.4 can now be
controlled by a checkbox in Options -> Rendering (I
think it's the Rendering tab, not at a computer right
now). Then, you can selectively turn it on for layers
where simplification would help speed up rendering.<br>

<div>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 <a moz-do-not-send="true"
href="http://naturalearthdata.org"
target="_blank">naturalearthdata.org</a>
this problem disappears. You can switch to
other world projections with no problem.<br>

<div>I don't think the image came through, but
the problem is that every polygon ends up as
a trapezoid, so I end up with a collection
of overlapping trapezoids<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>

Any idea what might be going on, and how
