    Description

      Since upgrading from 5.4.1 to 5.5.0 (both via community online installer MSVC2012 32 bit), some of our users with lower end windows machines report the following bug:

      class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(class QFlags): Could not initialize EGL display: error 0x3001
      
      class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(class QFlags): When using ANGLE, check if d3dcompiler_4x.dll is available
      
      Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior 2, swapInterval 1, profile 0) . This is most likely caused by not having the necessary graphics drivers installed. Install a driver providing OpenGL 2.0 or higher, or, if this is not possible, make sure the ANGLE Open GL ES 2.0 emulation libraries (libEGL.dll, libGLESv2.dll and d3dcompiler_*.dll) are available in the application executable's directory or in a location listed in PATH.
      

      d3dcompiler_47.dll (File modified in march 2014) as shipped with 5.5.0 is in place.

      We force Angle in out main() using since we previously had massive problems with broken OpenGL drivers:

              #ifdef Q_OS_WIN
              app.setAttribute(Qt::AA_UseOpenGLES, true);
              #endif
      

      I cannot reproduce the issue on any machine I have access to but I think it's worth writing everything down that I have.
