  On wayland, without this patch with OpenGL 3.2 version requested, it fails with error: 
  F5796592: wayland before.png <https://phabricator.kde.org/F5796592>
  and outputs in terminal:
  
    Could not get requested OpenGL profile, requested QSurfaceFormat::OpenGLContextProfile(CoreProfile) got QSurfaceFormat::OpenGLContextProfile(NoProfile)
    Could not get requested OpenGL profile, requested QSurfaceFormat::OpenGLContextProfile(CompatibilityProfile) got QSurfaceFormat::OpenGLContextProfile(NoProfile)
  
  With this fix, it loads, and shows that opengl version is only 2.1:

  With this fix, on X11:
  F5796603: kinfocenter X11 after.png <https://phabricator.kde.org/F5796603>
  
  This code in kinfocenter was added 4 years ago in commit: https://cgit.kde.org/kinfocenter.git/commit/?id=dc62d965ff21c9840b3284acbb91f7b44bd9e394 from review: https://git.reviewboard.kde.org/r/115952/ but I don't understand why 3.2 is required. :)
