Geoshow showing missing data

Hello,

I am having a problem with my figure showing missing data always only on the very top line of my map. I am using the following code:

load topoMap % grid data (65x130 double)
latRange = [-80 -15];
lonRange = [-40 90];
refvec = [1 max(latRange) min(lonRange)];
worldmap(topoMap,refvec);
geoshow(topoMap,refvec,'DisplayType','texturemap');

I've tried changing the lat/lon Ranges and have the same problem, always a few pixels missing on the very top line of the map. I've also tried changing the rendering with no change. Any ideas?

Thanks!

N.

If it helps to know, i have no NaN values in my data grid.
