Firstly apologies as I cannot show you a direct example on my site as still in local dev. On your demo site it can be seen though http://www.kriesi.at/themes/angular/slideshow-frontpage-example/, very small I know but the transition from the final slide back to the first jumps ever so slightly to the right. This has only come to my attention as I have overlayed some graphics onto the slideshow through the theme settings using html and css, the transition makes the graphic jump on fade.
As I say I can't show you the extent of this issue but it is noticeable to the trained ;-) eye on your demo. I have tried a few CSS tricks but can't get rid of this annoying issue.
Other than that wonderful theme and has provided a perfect platform for our company to relaunch as a fresher and more stylish company.
Your help would be greatly appreciated
