Yeah, good point -- it could easily call DRI3BufferFromPixmap for the window pixmap and have exactly the same access. > If this is a concern, Present could try allocating a new window pixmap > to unflip to, and just leave the last flip pixmap as the window pixmap > if that fails (which it "never" will, in basically any scenario where > the X server can otherwise continue working normally). Given your point above, I can't think of any reason to not just use the provided pixmap as the window pixmap. It does mean we'll be trusting that the application doesn't accidentally re-use the buffer at some later time, but as you say, there's no actual security benefit. -- -keith
