This appears to sort the problem re space below the widgets and I reckon probably should be included in the theme.
@media (max-width: 1024px) {
.inside-footer-widgets > div:last-child {
margin-bottom: 0;
}
}
You can see what happens now here on my temp default test site. This just has simple css and generatepress community version 1.3.34 installed.
It also seems to work okay at 100 110 and 125% zoom using chrome with respect to this issue.
