Star Ocean: First Departure

[Kai -X]

I play star ocean first departure on my ppsspp Android app. Use Redmi note 4. and it runs perfectly. But I stopped playing for a few months and now when I try to play it, it becomes shaky. The movement becomes shaky and stutters when I try to move diagonal, up or down, it doesn't do that if I move exactly horizontal. The sound also becomes stuttering and shaky. Its like when frame rate setting is not right. And so I tried changing frame rates and it always becomes worse with any of the frame rate settings. Please help me out, I love to play this game but with this problem I can't play it any more. Thanks a lot.
