Hi, I checked your page. It is OK in Chrome but in Safari portfolio items are stretched. Apply custom css code below, it should fixed it (I tried in Safari for Windows).

.portfolio-filter figure img {
  min-height: none;
  height: auto;
}

You easily can apply the code with simple custom css plugin.
