I can't reproduce the flicker issue here, but these are my performance
No significant difference on desktop (Ubuntu 12.10 64-bit, Chromium
22.0.1229.94) or these Android devices:
Samsung Galaxy Tab 10.1, Android 4.0.4, Chrome 18.0.1025469 (WebKit 535.19)
Nexus 7, Android 4.2.1, Chrome 18.0.1025469 (WebKit 535.19)
A collague of mine reports improvements on the built in browser on
a Samsung Galaxy Tab 2 10.1, though I can't verify that.
Performance is great on an Apple iPad 3, iOS 6 with your latest CSS.
