Note Edge lag

[AC Question]

I just bought a Note Edge - very nice except for one thing. Scrolling in Twitter app is horrendous.very Jerky and slow.
I have already adjusted animation settings in developer ops. Uninstalled and reinstalled Twitter.
Nothing works. I don't have this problem on my Note 3
I would be grateful for any ideas please

I think it's Twitter.... It jerks and stutters on my nexus 6 as well. I don't think the app has been optimized for the increased resolution... FHD to QHD is a big jump and they might not have bothered to address it yet.
