A: Worst. Gotcha. Ever. It happens because your full screen application window is specified as full screen. There seems to be some optimization stuff going on with the hardware rendering engine for fullscreen applications, probably in order to optimize framerates in pure OpenGL games. To fix it, tell android that your application doesn’t need to be full screen. I got the clue from this stackoverflow thread.
In the end, I simply changed the theme of my application from android:theme=“@android:style/Theme.Holo.NoActionBarFullScreen” to android:theme=“@android:style/Theme.Holo.NoActionBar” in my AndroidManifest.xml file.
