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.   Download: https://github.com/0xC0000054/NormalMapPlus/releases
