Created attachment 8585587 slow-borders.html
Here's an example where scrolling is unusably janky on OSX, with a retina screen:
http://www.2ality.com/2015/03/es6-generators.html
When I plugged in my external non-retina monitor to reduce, the jank is almost gone entirely--but it's still not as smooth as Chrome.
There's a single CSS class in this reduced version of that blog page:
.post-outer { border: dotted 1px #ccbb99; box-shadow: 0 0 0 rgba(0, 0, 0, .1); }
