In QGIS, whatever might be the source, I couldn't zoom beyond the scale of 1:2256.
Whether it's a raster or vector, result is the same.
Does anyone know how to fix this ?
On @Chris' advice I've uninstalled "Tile Map Scale Plugin" which fixed the problem (at least for me).

You need to uninstall 'Tile Map Scale Plugin' :) If you don't have this plugin installed, perhaps the same problem can be caused by another plugin, so try uninstalling all plugins and see if that fixes the problem.
