Yes. It's that image which seems to not refresh on deeper pages.
Is it the one on the left or the one on the right? Both of those are positioned via CSS, not javascript, so my guess is that this thing actually makes your browser have a FPS drop, and as such the image will appear to be out of position. For me, in Chrome (Windows 7), it works fine. I checked the console, you have one error there (related to google ads and something about unsafe javascript, so I guess it is Chrome here that blocks it). There is one error that is caused by this, and you solve that by editing the template smashing_lights.css, find:
Code:
background:transparent url(image/bulbs-50x50-fragments.png) no-repeat 0px 0px;
Replace that with:
Code:
background:transparent url(lights/image/bulbs-50x50-fragments.png) no-repeat 0px 0px;
