Twenty Fourteen: swipe touch events on slider have a slight delay

[sonjanyc]

Slight delay on swipe touch events, like on an iPad or iPhone.

To repeat

1. Swipe with your finger between slides
2. Note how the swipe event starts with delay and sometimes overlays a half or less, then stops for a second and then completes to show full next slide.

@Frank Klein is looking at this one.

Severity is low on this, nice to fix but not a blocker for 3.8 release.

For the 1. case (swiping) I am not sure,
but probably "FastClick" ​https://github.com/ftlabs/fastclick could help to solve case 2. and 3. (seems like a normal "click").

[lancewillett]

I think cases 2 and 3 are fine -- it's 1 we need to patch.

This has been an issue I've noticed with FlexSlider since (I believe) the original pre-WooThemes FlexSlider (v1).

[lancewillett]

@kwight Interesting ... good to know. I'll ping the authors to see if they have an opinion. Did you see any open issues in GitHub related to it?

[kwight]

No I didn't see anything related, but FlexSlider gets very little love on GitHub (470+ open issues).

I can't reproduce 2 and 3 on an iPhone 5s using iOS 7.0.4 but do notice a slight delay with swiping in number 1.

I can reproduce issue 1 on an iPad where the same delay seen on the iPhone becomes more noticeable.
