The attached test program works fine on my laptopt (intel graphic with
i915 kernel driver).
However, it does not work on my desktop, with a Titan nvidia card and
the latest nvidia driver (x86_64, 381.09). If I hit the "q" key the
program exits correctly, but I'm not able to rotate the cylinder using
the mouse. Everything works fine, instead, if I call iren->Start() from
main and not from a separate thread.
I'm really clueless, and would really appreciate any help in sorting
