      Description

      Try to run our application ( Deployed with Qt dll's & plugins)

      0. Get OpenGL error when starting application in DualView, OpenGL error 1280. No model rendering in our application.
      1. Change NVIDIA multiple display mode to Horizontal Span.
      2. Started our application in this display mode (1)
      3. The OpenGL model is rendered as it should
      4. While our Application (2-3) is still opened, change NVIDIA multiple display mode is set to DualView
      model is displayed in proper way in OpenGl
      5. In our apllication open up a new model - OpenGl still working
      6. Start another (second) instance of our application, while application 1 is open - OpenGl still working
      7. If we close all our applications - in DualView, and start application again & try open same model, OpenGL fails
