CCRenderTexture problems on Android

Hi. I’m using CCRenderTexture to post process a particle Node. On iOS, it works perfectly. On the Android Emulator it works with flickering. On an Android device the whole RenderTexture is invisible. You can sometimes see a tiny flickering of a part of the render texture, but that’s it.
Has anyone experienced similar problems with CCRenderTexture on Android and knows the source of such errors?
