Bug in Non-buffer Render + Frameskip! :(

[ysangredevago]

I wanted Report this problem to the developers,
I thought it was a problem only in some games,
But I've noticed that the problem occurs in all games I've tried (and that before me builds worked fine in v0.8.1)
1)When active frameskip + non-buffered render the bottom half of the screen displays graphics errors ...
2)When frameskip + disable non-buffered render, the picture looks good, but the game runs too slow.
3)When Render Active frameskip + buffered, the game runs at an average speed, but the image looks more pixelated.

The error is shown to me in the following games:
Dragon Ball Shin Budokai
Dragon Ball Shin Budokai 2
Rurouni Kenshin
Megaman Maveric Hunter X
Crash Tag Team Racing
Hellboy The Science of Evil
And surely the problem is not in these games, if not in general the emulator, since in the PC version of the same thing happens.

My device is an Xperia Play ..
I hope can be resolved in future reviciones since emulated speed is excellent with these settings:
Rendering Mode: Non-Buffered Rendering
Frame Rate Control:
Frameskip: +3
Force Max 60 FPS: Yes
Alternative Speed​​: 100%
