Nope. The slow page turns are ePUBS and the rendering engine has not changed. It is definitely fixed already in what we will ultimately receive. One of the things I noticed is that as development happens, some very basic things occasionally go wonky and have to be messed with again.
The new backend is for Kobo's proprietary kepub format only.
