I seem to have a bogus problem.. I''ve done a small OpenGL program that draws a fighterplane (looks like a F-16 or something similar).. But there is one small annoying problem. When i run the program in windowed mode then everything looks perfect. If i switch to fullscreen mode, then some polygons show through the figher-model. I''ve enabled glCullFace(GL_BACK) and assigned normals to every polygon (triangles). Still some of the polygons are visible (not always) through the rest of the model... They get more and more visible if the fighter is renderd further away from the viwer... Can someone here help me out with this problem. // Geron
