Does anyone know how to solve this? whenever i try to render a polygon using the gl utilities function (eg. gluSolidSphere, gluSolidCube), these never show when i go fullscreen or when i switch back to window mode. Some times they do show, but then the light is flickering... could it be some Z buffer problem? thx in advance

Remember to clear you viewport/render target every frame. I don''t know anything about OpenGL but if you forget to do so in DX something similar to your problem will happen.

Real programmers don't document, if it was hard to write it should be hard to understand

Check to make sure that the near Z plane is not 0...
