Swipe sensitivity in Ionic Slidebox + Android 4.4.4

I have scrollable content in each slide of an Ionic slide-box.

Everything worked perfectly, great user experience until I updated my Galaxy S5 from 4.4.2 to 4.4.4 this morning. Now the UX is an absolute nightmare. Scrollable content inside a slidebox is very difficult to work with. Side to side swiping sensitivity is super super high and prevents vertical scrolling unless absolutely perfectly vertical.

Tap-hold gestures are also really difficult to engage (again due to the side to side swipe sensitivity).

I have noticed this on my wife's Nexus 5 as well (which has always been running 4.4.4).

I am going to need to find a solution to this ASAP, since my Galaxy S5 is my primary demo device and it is a total train-wreck to work with now.

I recently updated to Ionic beta13, no change. As in, a complete app UX fail, an embarrassment to have out in the wild.

I also uninstalled the Chrome update that came with Android 4.4.4 (37->35) in the hopes that the WebView would be downgraded to a previous version, no luck.

I'm wondering if there is something specific about my HTML setup, or what else I could provide to get at the issue. I'm surprised I haven't seen more activity on this issue, because it is making my previously smooth app completely useless. It leads me to believe that it is an isolated problem, but I don't know where to start.

Attached is an HTML template where this is happening to me. Any thoughts greatly appreciated.
