Hi Yonggeng!

Thanks for your result. The drawing loop is crashing. We plan to change
the drawing loop, anyway - because it could be possible that in some
cases it might not work. Unfortunately this is your case.

I'll try to code now some kind of quick fix for you. But I'm not sure if
it will work... It will take me some time.

Meanwhile please check if callback example from QGLViewer works for you,
because I want to use the callback mechanism to fix this problem.
