Weird ibooks glitch

I recently bought an ipad air and updated it to the current update (8.1).
Using ibooks in list view, every second or third time I close a book and return
to view the list, the whole screen goes blank for about half a second and
sends me all the way back to the top of the list. I have many books so
this is very annoying, but i don't know if it's the new ipad or the update.

Is this happening to anyone else who has downloaded the new update?
Or do I just need to take the ipad back to the store to get fixed?

I have tried closing ibooks and reopening, shutting down the ipad and
rebooting, and I even tried restoring to factory settings, it's still doing it.

Thank you for any help or advice you can give.
