During Quantal Beta 1 install slideshow does not appear correct

[Carla Sella]

During test of image: http://cdimage.ubuntu.com/daily-live/20120903.4/quantal-desktop-armhf+omap4.img on a Panda board, at Point 20 "Wait for the installation to proceed and the slide to change automatically" of testcase: http://iso.qa.ubuntu.com/qatracker/milestones/232/builds/22473/testcases/1300/results the slide show does not appear correct but with side bars on the right side and on the bottom.
After a while the screen has a grey backgroud and then after another while the slideshow appears again, but correct but you can't change slides clicking on the left or right arrow.
See pictures attached.

I see this also on other variants, specifically amd+mac at the moment. It's also worth noting the pangolin logo on the slide Carla attached
