Safari Mobile (iOS 7.1+) Performance Issue

[th3d0g]

There a massive performance issue in Safari Mobile on iOS 7.1 (not an issue on older versions).

This is actually caused by the canvas size being scaled due to the default CSS properties.

content {

height: 100%; width 100%; }

Suggest removing these as the defaults for now, until a more elegant solution is found.

My approach for filling the browser window was the set the Viewport meta tag. Not the most elegant solution, but works fine. See here: https://gist.github.com/th3d0g/fe409ee3791493eb581e
