Your best bet is to download a third party launcher. Nova launcher will make a fairly close approximation of the Pixel launcher. You might also check out the lawnchair launcher.
Scrolling isn't working for me on Nova Prime, using a 4320x3040, 502dpi, jpeg. What really blows is this issue was posted Tuesday...while I was running all 9 updates available for my brand new Note UPS just delivered. Oh well, maybe not the biggest issue in the world right now.
And the gravity sensor needed for live wallpaper provided by Google is also not working. Given the third party launcher would disable one of the full screen navigation gesture option, now we have to choose either using a boring wallpaper or a uncomfortable navigation gesture.
