    Well. The last problem has already been solved. If you wish to know the origin of my question, I think the best way is to get an ATI card and write some stencil blitting code, then you will know the...

    Well. I'm very gratitude to you for your help. After I checked your answer and modified it to something like GL_DEPTH24_STENCIL8, I get my code run smoothly again. But this is not wholy my fault at...

    Thanks a lot, Dark Photon!

    At first, I also think it may due to the bandwidth between CPU<->GPU. But after I modified the code to

    Why no one answers? Is there anything not declared clearly?

    I have written a very simple program but with fbos.
    That program can run smoothly under ati card pcs but report error on nvidia card pcs.

    Well. You seem to be irritated though I dunno why.

    A specification has announced everything properly while an implementation announced none other than the specification's.
