From time to time, I'll deploy my app and when I fire it up all I get is a blank screen.  The body seems to have the "ui-mobile-rendering" class applied to it, which sets it's visibility to "hidden" and it never recovers.  This issue *may* be specific to Firefox, as I don't recall seeing it in Chrome.  But, I use Firefox for most of my development due to Firebug.

Please let me know if others have seen this, or if I can provide more info to help get to the bottom of it.
