How do I disable vibration when swiping down on the lock screen?

When I swipe down to unlock the phone, it vibrates.

I tried the advice offered for other phones. None of it worked. I have managed to disable the haptic feedback everywhere else. Thanks.

Lag when swiping away recent apps

I'm running Lollipop 5.1.1 and whenever I swipe away recent apps in the task switcher such as Chrome or Play Store, there is a lag/stutter before the app leaves the screen. It swipes away and then pauses for a second before leaving. Is there any way to fix this.
