[Haskell-cafe] hawiki Haskell SDL openGl example works strange

[yin]

Hello, again,

I tried to run the example from http://haskell.org/hawiki/HaskellOpenGl
(the SDL version), but the scene is shown, only when I resize the
window. I tried to insert the drawGLScreen before mainloop call, but it
didn't worked. Do you some idea how to resolve this little problem?

Thanks
