On some devices like the Nexus 7 or Samsung Galaxy Nexus (possibly others), I noticed this issue (See picture). This is running on Hardware Acceleration Mode in a WebView. H
Thanks to Delyan for solving the issue. How he told me to solve it was to add -webkit-transform: translate3d(0,0,0) to all parts that move.
-webkit-transform: translate3d(0,0,0)
KUDOS DELYAN!
