    • Windows 10 64 Bit. Tested systems: Dell Optiplex 3010 (i5-3470) and Surface Pro 3 (i5-4300U)

    Description

      When drawing a very simple shape using QPainter on a QOpenGLWidget, both the Intel i5-3470 and the Intel i5-4300U do not show anything when requesting an OpenGL-Context Version 3 or above.

      When requesting a GL 2.0 context, the shape is shown

      (Commenting line 13 of main.cpp of attached example)

      Both graphics support OpenGL 4.3 and run a rather complex OpenGL scene without problems.
