For future reference, I had been plagued by this issue as well ever since getting this phone. For me, fast scrolling was just fine--it was only evident when doing slower scrolling, like scrolling slowly through the application drawer. The display would hitch repeatedly, as if the graphics buffer could just not keep up.
For me, disabling
the developer option "force GPU rendering" has removed the problem for me. I swear I tried with and without this option before but it's working well for me, so now I have one less irritation with this piece of hardware.
