Hi,
My Boox Leaf 2 used to work great for me when I still had the per app settings of refresh every X actions and Animation filter setting. I had it set for a 3rd party app and it worked great for me.
Since this was lost in a firmware update, I find myself unable to find a good setting that minimzes page turn animation, minimizes ghosting but still does a speedy page turn.
What are you using for reading? Speed? Any other optimiztion possible?

Thanks!
