Hi Paolo,

If you open grib files in QGIS, off course it is GDAL who is responsible
for that :-)

I played a bit with netcdf/grib files recently, found some problems and
reported these in trac.osgeo.org/gdal and those were picked up/fixed by
Even Rouault pretty good:

https://trac.osgeo.org/gdal/ticket/7103

https://trac.osgeo.org/gdal/ticket/7104

https://trac.osgeo.org/gdal/ticket/7086

Not sure if your problem is one of those, but maybe you just have to
wait for a newer gdal version ;-)
Or create issues for it?
