One of my course attendees had a strange problem on her iPad.
During a crossfade from one state to another (as a tabbed panel)
the overlayed elements (some texts) appeared with a slight ring
of strange jitters around it. See for yourself, I took a screenshot:
I See these very often on my iPad1. Wanted to start a thread as well.
They go away after a few slides or when they loop (saw that on things I use
for flashing elements).
Thanks for the "me too" confirmation. She was using an iPad 1.
I can tell her now not to blame her folio or suspect a faulty iPad.
I'll try the same folio on an iPad 2, to see if there's a difference.
Sorry to jump in late, but I have definitely seen this in the v18 tools. I had MSOs flashing a page-turn arrow on and off slowly but had to remove them all because they were producing exactly the same kind of 'noise' distortion as in your screenshot.
