It does not in my case, if I use a vector on ED50 UTM31 and the
project set to a custom projectione defined as
+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0
+y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs
and onthefly activated: the vector is displaced ca. 100m vs the google
raster. This also happens with click-fu.
