This could be the FAQ where DirectX sets the FPU precision to
single, which starts to clobber double lua_numbers.  I think
there was a thread about it quite recently (or maybe I'm mixing
up this list with one of the many others where people get frequently
hit by the same DirectX misdesign... sigh...).

There's a DirectX init flag which causes DirectX calls to preserve
the FPU state, which is anecdotally a speed hit but avoids the
problem.  Using OpenGL is also a pretty good workaround. :D
