Solution 1:

Black boxes generally occur when the bitmap resource for an Image is no longer available (such as set to null or recycled).

In an openGL view, this can occur when an activity goes to the background, often because of lost context. A good place to start would be looking at the GLSurfaceView documentation, in particular the method setPreserveEGLContextOnPause(...).

Solution 2:

Adding android:hardwareAccelerated="false" to the <application> manifest is a workaround, however does not solve the problem. OpenGL state and context preservation as mentioned by Phil might play a role here.
