GL_DEPTH24_STENCIL8_EXT not working ok on NVidia and Intel. ATI doing fine

Hi, I am having compatibility issues between graphic cards, when using FBO and stencil buffers: it only works correctly on ATI cards, NVidia (GeForce GT 620) and Intel (HD Graphics 4000) fail (they operate as if the stencil buffers were not enabled). I made sure I had the last drivers. Any idea what I am doing wrong, or what is going on? Here my code: glGenFramebuffersEXT(1,&_fbo); glBindFramebufferEXT(GL_FRAMEBUFFER_EXT,_fbo); glGenRenderbuffersEXT(1,&_fboDepthBuffer); glBindRenderbufferEXT(GL_RENDERBUFFER_EXT,_fboDepthBuffer); glRenderbufferStorageEXT(GL_RENDERBUFFER_EXT,GL_DEPTH24_STENCIL8_EXT,resX,resY); glFramebufferRenderbufferEXT(GL_FRAMEBUFFER_EXT,GL_DEPTH_ATTACHMENT_EXT,GL_RENDERBUFFER_EXT,_fboDepthBuffer); glGenRenderbuffersEXT(1,&_fboPictureBuffer); glBindRenderbufferEXT(GL_RENDERBUFFER_EXT,_fboPictureBuffer); glRenderbufferStorageEXT(GL_RENDERBUFFER_EXT,GL_RGB,resX,resY); glFramebufferRenderbufferEXT(GL_FRAMEBUFFER_EXT,GL_COLOR_ATTACHMENT0_EXT,GL_RENDERBUFFER_EXT,_fboPictureBuffer); glBindFramebufferEXT(GL_FRAMEBUFFER_EXT,_fbo); The FBO functionality works fine with all tested graphic cards. Only the stencil buffer functionality fails with above mentionned graphic cards. Thanks for any insight.
