Default Custom Lock Screens turning Talkback on

Yesterday I've tried several custom lockscreen apps - they all needed to be turned on in accessibility options in order to process notifications. However, this also instantly was turning Talkback on - even though it was still listed as off in accessibility menu, I was hearing things like "Page 2 of 2" when I was scrolling through my homescreens.

This is really annoying and basically doesnt allow me to use any custom lockscreen...

My phone is stock, unrooted 4.1.2
