hi can anyone who has flashed stock XXKG2 confirm that the bouncy effect while scrolling is working fine?

i'm running my own deodexed rom and notice the bouncy effect seems erratic. For eg, in Setting it works fine. In market also fine, but if I go to the apps description page...no bouncy effect, it just stops when get to the bottom.

Same with 3rd party apps, some is fine and some totally no bouncy effect.

I just want to confirm if stock firmware is working fine or if it's a problem with my deodexing process. thanks..
