mac abnormal and multi-layer shaders

[zijii]

Hi all,

I have tried ppsspp on both windows 7 and mac 10.9 mavericks. On windows, it works perfectly, however, on osx, during the playing, there are multiple layers of shaders.

For example, there is tree on the side of roads, but I can see the shades of them just in the front.

Here is a picture link (sorry I haven't found a way to paste picture) :

Thank all!
