Looks like you need to flush the graphics commands.
try this:
// displayCallback $= clear [ ColorBuffer ]
displayCallback $= display
display = do
clear [ ColorBuffer ]
flush
Did that work?

Hello,
The program:
import Graphics.Rendering.OpenGL import Graphics.UI.GLUT
main = do _ <- getArgsAndInitialize createWindow "Hello World" displayCallback $= clear [ ColorBuffer ] mainLoop
and the problem: The ColorBuffer is not cleared, the window shows what was there before it was created. Creating windows, drawing points,... works all well, but "clear [ ColorBuffer ]" seems not to work. (I'm using the ghc 6.6 on Windows)
Thanks in advance for your help.
