Yes, I often have some degree of trouble. If I am conscious to give a
deliberate vertical swipe, it works fine. But my default
not-thinking-about-it swipe tends to have some horizontal motion in it that
sometimes gets interpreted as a scroll. Usually I suspect this is my fault
for not being vertical enough.

The one that bugs me is though is when my mostly-vertical swipe does work
to kill the app, but only after there has been some left/right scroll
motion. It then snaps the app back to the center before it does the kill
animation. That snap is a little disorienting and I have to mentally pause
for a second to verify that it killed the one I wanted to kill. (This is
easy to see if you intentionally swipe diagonally from the center of the
screen to one of the upper corners.)

It feels like the scroll is a little too responsive? I wonder if we could
wait a beat on the scroll animation until we decide whether this is a
really a scroll or a swipe. Or alternatively let them both happen at the
same time but eliminate the snap and just let the killed app shoot off into
the ether as it is also scrolling away?
