Avatar moving not smooth with FPS between 55 and 60

[Dorian]

Hi guys

I'm working on a game developed with phaser.JS (and phonegap), and i'm facing a surprising problem. FPS is pretty good (it's between 55 and 60) but the avatar moves are not smooth. So i guess it's caused by the use of phaser feature.

You can see the problem on the video here : https://www.youtube.com/watch?v=JfYBcvl4b78

Have you ever met this problem ? Do you have some idea to improve that ?

 

Thanks for your time !
