Hi all, I just installed lwjgl 2.9.0 according to site instructions. i copied the basic DisplayExample Demo from the lwjgl site and get no compile errors. I run the code and i get a window of the requested size but the content is a flickering set of black and white horizontal stripes. No runtime exceptions are reported. when i comment out rendering at line Display.update(); then the flickering stops. anything wrong in the way i followed the instructions or are instructions wrong? i am using eclipse on mac os 10.8.4. any suggestion greatly appreciated. thanks,
