Interestingly enough I had a go with a similar scenario in Windows 10
(using the built-in drivers) and it seemed to be OK.

I guess the Windows 8.1 default OpenGL renderer is different to the
Windows 10 one. It may be a Windows 8 only issue (which might mean it
goes away pretty quick?!? :)

Thanks for putting it in the docs anyway.

Title:
  "OpenLP has stopped working" when OpenGL not installed on Windows 8.1

Status in OpenLP:
  New

Bug description:
  I recently upgraded a laptop to Windows 8.1 and experienced problems
  starting up OpenLP.

  After the initial setup phase, when attempting to start OpenLP. I got
  the error "OpenLP has stopped working" and the application crashed.
  This worked fine under Windows Vista.

  After some investigation, I discovered that OpenLP was crashing after
  'Init done for SlideController' in the debug log (see below). I
  checked out the log on a working machine and saw that normally after
  this code in openlp.core.ui.maindisplay is run, including the
  following code:

          if not is_macosx():
              self.setViewport(QtOpenGL.QGLWidget())

  This rang a bell as I had struggled to get other OpenGL apps working
  on the laptop post install. After checking the Intel website, I
  discovered that the laptop had an Intel 965 chipset, but the default
  drivers that come with Windows 8.1 do not support OpenGL. I downloaded
  the last Windows 7 set of drivers available for this device
  (win7_1512754.exe) and installed them on the laptopm even though they
  were 'older' than those included with Windows 8.1. After rebooting,
  the problem went away.

  If this happens again it is worth people upgrading their graphics
  drivers if they are still using the built-in Microsoft ones (if the
  device name contains the words 'Microsoft Corporation' in Device
  Manager). It would be helpful if OpenLP could detect if the current
  drivers support OpenGL properly. If they don't, it probably shouldn't
  attempt to initialise the viewport with OpenGL enabled, to avoid the
  crash happening for others.

  Debug log for crash follows:
