Sometimes the buttons and background loads and sometime it doesn't. Background colors disappearing etc.

The project is to big for me to show and i can't really say that I have a special source of the problem.

I guess that I just want to know if there are problems with the combination android 4.2 and jQm? I noticed that 4.2 wasn't on the list over tested OS's..

edit: I am using phonegap/cordova, but that doesn't seem to be the problem.
