X11 error: Resource temporarily unavailable

Ibrahim

Hi, I'm using Deepin OS 15.4.2 and Qt 5.9.2. I created a QtQuickControls 2 project and I added this code in main.qml:

...
import QtMultimedia 5.9
...
ApplicationWindow {
  visible: true
  width: 640
  height: 480
  title: qsTr('Example')

  Audio {
    id: sound
    source: 'qrc:/sounds/audio.mp3'
  }
}

When I run this app, I see this output and it's not working:

QML debugging is enabled. Only use this in a safe environment.
The X11 connection broke: No error (code 0)
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
      after 35 requests (35 known processed) with 0 events remaining.

What is the problem?
