Tekken 6 legs and feet shaking!

[TekkenKing]

Hi, i am new here so first of all i want to say conrats to the forum and thank you so much for helping us to get playing some PSP games on PC in the most easy way!
So about my qestion i'm running ppsspp the latest version with 60FPS all the time but the main problem is that when i'm playing Tekken 6 i'm getting a bit of shaking of legs and feet, so does anyone know if this can be fixed or we need to wait until we get a new version of ppsspp with bug fixes ?

Here is a link of video doing that:
