I just installed the new version of commerce kickstart and noticed after updating the logo to a different logo the slideshow started to glitch when I load from a clean browser history in safari, i have not tried mozilla yet but will test this on other browsers and let you know. The slideshow shows all 3 slides one right under each other down the start page. The view takes a minute to correct but will correct it's self eventually. It seems if you do nothing it does on for longer. If your clicking or moving a lot it seems to speed it up a bit but not a lot.
Not sure if that helps a lot but hopefully it helps some. Thanks. I will let you know if I find any workaround.
