      Qt 5.10.1

      Intel I7 8650U with intel 620 UHD Graphics Card (Driver version: 15.65.5.4982 - 27/03/2018)

    Description

      This is probably a driver related issue, but I could not diagnose when the issues was occurring. 

      Essentially, I found that embedding a Scene3D item inside a QtQuickControls 2 MainApplication, the application would crash the Intel OpenGL Driver when the user resized the window. This is for a Windows 10 system. 

       

      ApplicationWindow {
      id: window
      visible: true
      title: "Application Title"
      
      width: Screen.width * 0.8
      height: Screen.height * 0.8
      
      Scene3D {
      anchors.fill: parent
      aspects: ["render", "logic", "input"]
      focus: true
      id: scene3d
      
      MySceneEntity { id: sceneEntity }
      }
      
      }
      

      I knew this was a driver specific issue because this never occurred developing with an Nvidia Graphics Card. I could not find any way to fix this, even updating to the latest drivers. By chance, disabling the following options in the control panel stopped this from occurring:

       

      Disable: Application Optimal Mode

      Disable: Anti-aliasing features 

      Vertical Sync: Use application defaults

       

       

       

      I am not sure if this is specific to Qt3D, or a bug within the intel drivers themselves. However, I provide this as reference anyone who encounters similar issues.
