Thanks for the explanation

glSurfaceView.getHolder().setFormat(PixelFormat.RGBA_8888);

This gives you a translucent surface, which means that any pixel that is not drawn completely opaque will be blended with whatever window is behind your app. It will affect your performance btw.

 

Should I change the surface view format to RGB_888 instead?

Yes, that will fix your problem and improve perfornance.

Is your SurfaceView marked with the transparent pixel format? If so, what you are seeing would be expected. If your SurfaceView is opaque then you *must* draw every pixel opaque on screen.

I got a big problem with a game of mine and the latest version of Android. Semi-transparent pixels rendered on the OpenGL ES surface let the underlying activity shine through as following screen shot shows.

This problem only appears in a new "AppGratis" promoted version of the game I just released this morning and here is the really bizarre thing: ONLY the APK downloaded from Google Play has this problem. When I install the same APK that is locally stored on my computer via adb I do not have this problem.
I re-installed the Google Play version multiple times and the rendering artifact is always reproducible.

It looks like Google Play alters the APK or maybe it is incorrectly installed on the device. However, I do not even know what may trigger that "shine through" effect. Any help (especially from Google) appreciated.
