    Description

      When QML application goes to background due to HOME button is pressed, application output receives burst of EGL_BAD_SURFACE messages end app crashes after some time.

      The message sequence that keeps repeating after pressing HOME button is the following:

      W/Adreno-EGLSUB(24892): <DequeueBuffer:606>: dequeue native buffer fail: No such device, buffer=0x0, handle=0x0
      W/Adreno-EGL(24892): <qeglDrvAPI_eglSwapBuffers:3688>: EGL_BAD_SURFACE
      W/Qt (24892): eglconvenience\qeglplatformcontext.cpp:319 (virtual void QEGLPlatformContext::swapBuffers(QPlatformSurface*)): QEGLPlatformContext::swapBuffers(): eglError: 12301, this: 0x789662e0
      W/Qt (24892):

      I should emphasis that this behavior began since Qt 5.3.0 (I noticed it on RC also), while the same apps worked perfectly with Qt 5.2.1.

      I attached demo project that I used for testing, and raw application output (part of it).
