I believe there's a bug in the VC column padding when choosing:
Column padding: none
Column Padding Position: All sides

in responsive.css?ver=8.0.1:785 , this definition still quicks in:

@media only screen and (max-width: 1000px) and (min-width: 690px) {
.one-fourths.span_3,
.one-fourths.vc_span3,
.one-fourths.vc_col-sm-3 {
        padding: 15px;
    }
}

there may be other occurrence of this problem elsewhere

if this is not a bug, but is by design, the problem is that this leads to content within these not 100% width columns  being unaligned  with content that occupy the full width

the workaround being to having to select a Column Padding Position that does not affect left or right
