Based on harold's public domain plugin that he no longer supports (LINK). Note that the source is based on output from Reflector and i've done little so far besides getting it working.

I am on the Windows 10 Creators Update so I am not able to rollback the .NET Framework version,
but that would concur with my testing that the crash appears to be caused by a regression in the .NET 4.7 JIT optimizer.
@Ego Eram Reputo @Rick Brewster
Using the MethodImplAttribute to disable JIT optimizations for the OnRender method has fixed the crash.
