Hello Gerhard.
This is caused by a rounding in xsane-back-gtk.c line 2218
in function:
static void xsane_back_gtk_value_update(...)
case SANE_TYPE_INT:
val = adj_data->value + 0.5;
remove the "+ 0.5" and it should work.
But I am not sure if this will cause other problems.
I think there has been a reason for adding the "+ 0.5"
