I'm fairly sure that's due to main.c:173:

173	    Rast_set_window(&hd_band);	/* Antes de out_open y allocate para mismo tamaño */

If you actually want to calculate each band at the input's native
grid, you need to open and close the base map for each band.

Also, I'm quite sure that this is wrong:

156	dem.type= Rast_open_old(base->answer, "");

It should presumably be Rast_map_type() (or use Rast_get_map_type()
instead).

I have no idea how the display driver comes into this.
