I encountered a problem in QGIS 2.18.21 with printing or exporting my Map Composition into PDF. The layer composition has:
one vector polygon layer (either 4326 or 3857)
one baselayer (either Google Road/Terrain or OSM)
I tried all sort of combination:
print and export
my polygon in 4326 and 3857
Looking closely into the shift, it appears that the polygon layer and Google baselayer has different scale, as going eastward and southward the shift grow bigger.
Now to the question: how do I print/export my map composition with Google baselayer in it?
