Could this be a hardware/software/OS incompatibility? In 2012, there was no Windows 10 (Windows 8 was released, I think, in the fall of 2012), graphics cards were much simpler, etc. I could imagine that LabVIEW 2012 would not have code that took advantage of graphics features that were not yet available, which might explain why my Intel 630 chipset had no problems with the 3D Graphics example in LabVIEW 2018 running on Windows 10 ...
