First off - there are no NuGet packages specified in the project, so I have no idea what versions are you using. Also there's literally no OpenTK 1.2, only 1.1/2.0 at best, so I have a hard time getting this thing to compile even.
I'm on VS2022 though and I had to upgrade this project to .NET 4.8 from 4.5, as I can't download the targetting pack.
