New update... Scrolling animation not fixes yet

I asked about this previously and no one seemed to care that much to answer... I have a nexus 6p running 7.1.1 and using adobe reader... While reading documents scrolling seems to have an issue it's like you scroll the screen freezes for a second and then it start working again... And yes i used other apps like Google drive's pdf reader and no issue is there whatsoever... Thanks in advance
