Yup, and lag when the keyboard pops up.
iOS 8 in general is pretty fluid for me, similar to ios 7.1.2, especially while navigating arround, opening/closing apps, multitasking etc.
However there is definatly some choppiness I noticed.
1) Safari on iPad
2) weather app on iphone
3) music app on both
4) other random spots
I had no system crashes or freezes at all since updating and its far from the mess 7.0 was or people claiming 8 is.
