Description
When I use Natural Earth as data source and want to change projection for the project to customized Robinson, the map breaks apart (see attached file).
I use a projection as follows:
Proj4: +proj=robin +lon_0=150dE +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs
Hope if it's not a bug. But if it is, I'd like to know if there's a workaround.

There are limitations (for features crossing the dateline) when you want to reproject global data. One of the tricks it to generate a 0-360 map instead of a -180/180 one. I believe there is an example on the QGIS manual.

Seems that the issue has no elegant solution yet.

yes, but probably there are similar tickets already open (cannot do a search now). I would appreciate if you could give it a go, so we can eventually close the duplicates.

I've found that #13380 is closed due to "end of life" of QGIS 2.18 LTR. I will reopen this issue until wrap around works in future releases.
