White screen?!

[Icazo]

So I noticed that in the newest version of PPSSPP (1.0.1) for Android, some games have random light/dark "aura", making the game too bright or too dark (See the picture). It has to do something with lighting. The games that do that are Sonic Rivals 2, Kingdom Hearths and Ratchet & Clank. Does anyone have any idea on how to fix those, if it's even fixable? It drops game speed from 100% to 40%, so it IS a big problem.
Thanks for the help
