BizHawk 2.3.1 instantly crashes when selecting the OpenGL display method.

[fsvgm777]

Reproducing it is pretty simple. From a clean config, just select the OpenGL display method, then restart BizHawk. Upon restarting it, you'll almost instantly get this exception message:

System.MissingMethodException: Méthode introuvable : 'Void OpenTK.Graphics.IGraphicsContext.set_VSync(Boolean)'.
à OpenTK.GLControl.set_VSync(Boolean value)
à BizHawk.Client.EmuHawk.DisplayManager.UpdateSourceDrawingWork(JobInfo job)
à BizHawk.Client.EmuHawk.DisplayManager.UpdateSourceInternal(JobInfo job)
à BizHawk.Client.EmuHawk.MainForm.Render()
à BizHawk.Client.EmuHawk.MainForm.ProgramRunLoop()
à BizHawk.Client.EmuHawk.Program.Win32MainLoopCrashHandler.TryCatchFinally(String[] args)

It should be noted that the Direct3D and GDI+ display methods are fine.

EDIT: Forgot to mention that I didn't have this issue on BizHawk 2.3.0.

Reproducible on Win10 Home 1709, please try the dev build and confirm that the crash does not occur.

This looks like it's the OpenTK issue making its way in? The release build doesn't have #1380 merged in, but that commit fixed #1384

@NarryG Exactly what I was thinking.

Can confirm that the OpenGL display method does not instantly crash on the latest dev build.

(I'm on Win10 Home 1803, btw)

We decided not to include the monster unix PR into release just yet, and I felt like squashing it, so we can't extract the commit that fixes this bug without conflicts I guess.
