Well, depending on the game, this isn't a problem at all.
Most games that can be made in a sensible, optimized manner right now do not really suffer from that. The only case where it is really annoying is when you need super-smooth scrolling. It will be a while until that type of game can be expected to run on a really wide range of devices, if created with wrapped html5. Those you can safely do these days, single screen action games and puzzles, are quite forgiving when it comes to those micro-glitches.
