Help pls. Android 4.3

[Grimms]

I'll just clarify a bit.

The game I'm trying to play is FFT the war of the lions (european version). I did try Tactics Ogre also, with similar (but not exactly same) results. So Tactics Ogre doesn't work either (well, it works judging by the sounds, but the screen is really screwd up), and I think it's the same problem, but I only tried Tactics Ogre after this problem manifested, so I can't be entirely sure.

The screen rendering seems to be screwd up. When rendering resolution is set at 5xPSP I can see the screen divided into rectangles, in a roughly 5x10 grid. These may or may not be blown-up pixels, but as I decrease the rendering resolution the rectangles get bigger. At 1xPSP I can see maybe one and a half of these rectangles. Also the colors look like they might be inverted, or just otherwise wrong. As said, software rendering removes the problem, but slows down the game to be unplayable.

I too reinstalled PPSSPP but that had no effect.

Anyone else have this problem? Any ideas how to fix this?
