It seems that your graphics card has problems. What CPU and graphics card do you have?  
Do you see the same kind of errors when you run the latest Slicer Preview Release?  
Do you see errors right away when you start Slicer or only when you are doing certain operations?

A modification has been made in the slice project by myself, then the project has been rebuild, but the error only occured at the first time i run the program.

Is everything fine without your modification? What did you modify?
