Ipad 4 ios 7.1 missing animation

i recently updated my ipad 4 to ios 7.1 and when i did, i noticed that when i double click the home button or do the five finger swipe, which brings me to the recent apps open, and so then i noticed that there is not the animation i used to have before, i have enabled reduce motion on it and now when i go to the recent apps on my ipad 4, it is laggy and stutters because the animation is missing. i know the animation is missing because i put the same settings on my ipad mini retina and iphone 5 with the same settings, and i double checked that the animation is there, but it isnt on the ipad 4. please help or confirm this is true? and i hope apple fixes this issue in a future update and improves more speed enhancements and features.
