Hi Ryan,

> Switching the whole app to single-threaded works for both.

That's indeed strange. The snippet I provided might not do all the 
necessary checks however. I use a similar piece of code in my projects 
to ensure compatibility and it worked on a wide range of GPU/driver 
combinations at least on Windows and Mac-Platforms.

Can you create a minimal _compilable_ example, so more people might 
check what is wrong?

Cheers
Sebastian
