The major toolkits don't bother to use it, so presumably they think explicitly managing the backing pixmap is a better idea. > The Composite extension is not really an option on small framebuffer > devices .... Because? If what you mean is "small memory devices", DBE's not really a clear-cut win for you there either. You'll use less memory in the steady state of no named buffers in your client, but when you do have named DBE buffers (or whenever the DBE window gets resized) you'll need twice as much memory as Composite would, since DBE creates pixmaps for both the front and back buffers where Composite merely holds one offscreen pixmap. Don't let this dissuade you from completing the XCB support for it, but I _would_ dissuade you from trying to actually use DBE. - ajax
