Managed to find a solution with a bit of Google searching.
It regarded flickering of text in Safari and Chrome with CSS3 animations.
I added the following rule to the elements that were flickering:
-webkit-transform-style: preserve-3d;

Still need assistance on the logo positioning.
EDIT: The slideshow on the front page has disappeared for absolutely no reason. As a result, it has cut off any drop-down menu items that would normally appear - very frustrating (
