    Description

      I run Windows using VMware Fusion on my Mac. My application uses Qt3D.

       
      When I look at the OpenGL capabilities of Windows under VMware using "OpenGL Extensions Viewer" (http://realtech-vr.com/admin/glview ) it tells me that it is capable of using a 3.3 core profile:

      Renderer: Gallium 0.4 on SVGA3D; build: RELEASE;  LLVM;
      Vendor: VMware, Inc.
      Memory: 384 MB
      Version: 3.3 (Core Profile) Mesa 11.2.0 (git-b9d3786)
      Shading language version: 3.30
      I can run the real time tests for 3.3 and it works fine.
       
      No matter what I try from within Qt (5.9), I can't get it to give me that profile. If I request 3.3 Core, this is the "best" profile I can get out of Qt:
       
      OpenGL Info
        Vendor: VMware, Inc.
        Renderer: Gallium 0.4 on SVGA3D; build: RELEASE;  LLVM;
        Version: 3.0 Mesa 11.2.0 (git-b9d3786)
        Shading language: 1.30
        Requested format: (version 3.3, profile [core], depthBufferSize 24, stencilBufferSize 8, rgba BufferSizes (-1, -1, -1, -1 ), samples 8, swapBehavior 0, swapInterval 1)
        Current format:   (version 3.0, profile [none], depthBufferSize 24, stencilBufferSize 8, rgba BufferSizes (8, 8, 8, 8 ), samples 8, swapBehavior 2, swapInterval 1)
      I've tried all different combinations of versions and CoreProfile vs. CompatibilityProfile with no luck.
       
      qtdiag also only reports a 3.0 context (see Environment section - no surprise since I think I'm using the same method to request and check the context).
