      Description

      There are 2 simple QtQuick applications. Both consist of a Window which includes an Image. First application is targeting display 1 and second app display 2. This is achieved by passing a path to JSON config file to QT_QPA_QNX_DISPLAY_CONFIG env variable at runtime. Displays have different resolutions and are configured in QNX system config file with correct resolutions and settings.

      If executed separately, each application runs as expected. In case one application is already running and the other one is started, the second one will crash with the following log.

      QEGLPlatformContext: eglSwapBuffers failed: 3003
      qUncompress: Input data is corrupted

       

      Another test was conducted in which single application instantiated 2 windows, each targeting  a different display. This worked and it was possible to see the image on 2 displays.
