    Description

      -Create a HelloWorld project and add a BusyIndicator (like below)
      -launch
      -push on the home button
      You will get an infinite errors while in background:

      E/[EGL-ERROR](27091): void __egl_platform_dequeue_buffer(egl_surface*):1610: failed to dequeue buffer from native window (0x59e94a98); err = -19, buf = 0x0,max_allowed_dequeued_buffers 3
      E/[EGL-ERROR](27091): void __egl_platform_dequeue_buffer(egl_surface*):1610: failed to dequeue buffer from native window (0x59e94a98); err = -19, buf = 0x0,max_allowed_dequeued_buffers 3
      W/Qt      (27091): eglconvenience\qeglplatformcontext.cpp:332 (virtual void QEGLPlatformContext::swapBuffers(QPlatformSurface*)): QEGLPlatformContext::swapBuffers(): eglError: 12301, this: 0x59b0a898 
      

      These errors appears even if the BusyIndicator is invisible.
      -Write : "visible:false"
      -go to the background (no errors)
      -return into the application (errors appear)

      main.qml:

      import QtQuick 2.2
      import QtQuick.Window 2.1
      import QtQuick.Controls 1.2
      
      Window {
          visible: true
          width: 360
          height: 360
      
          Text {
              text: (g_busyIndicator.visible?"Visible":"Hide")
              anchors.centerIn: parent
          }
      
          MouseArea {
              anchors.fill: parent
              onClicked: {
                 g_busyIndicator.visible=!g_busyIndicator.visible
              }
          }
          BusyIndicator
          {
              id:g_busyIndicator
              anchors.bottom: parent.bottom
              anchors.bottomMargin: 200
              anchors.horizontalCenter: parent.horizontalCenter
              height:160
              width:160
          }
      }
