I noticed this problem at Nov.2010, and described it in a FAQ in Chinese [[开发常见问题答疑]], at the bottom of this wiki page, you can see this image
Is it the right one you see?
Some people fix this problem by update their video card driver, someone re-intall the whole windows system (omg, wtf!)…
But I do have no idea how to resolve it completely. It’s caused by the compatibility between PowerVR OpenGL ES 1.1 and the desktop OpenGL interface.
