iPhone4 blurred text/images after content load via ajax

i use phonegap, jqtouch and iScoll for a iphone app. I load some con开发者_如何学运维tent via ajax into a div container. After that, sometimes all elements blurred and sometimes not.

Strangely after i make a swap (-webkit-transform: perspective(800);) between pages, all looks sharp.

Is there any solution for my problem?

Thanks Kevin and sorry for the bas english
