Рендеринг в текстуру через объект framebuffer

Я инициализирую фреймбуфер. Затем в цикле я рендерил сцену в текстуру, обрабатывал ее шейдер и выводил экран. На моем ПК все ок. (Radeon HD 7870.) На другом ПК (GeForce FX 5200) функция glCheckFramebufferStatusEXT возвращает ошибку «8cdd» и отображает черный экран с частотой кадров 0-1 кадров в секунду.

Исходный код:

#include "main.hpp"
GLuint fbo, fbo_texture, rbo_depth;
GLuint vbo_fbo_vertices;
GLuint program_postproc, attribute_v_coord_postproc, uniform_fbo_texture;

Shader shader;

int main(void)
{
