Comment welcome. ### Double Buffering Double buffering on X is kind of a mess. Here's documentation on the [Multi-Buffering](XcbNotes/buffer.pdf) and [XDBE](XcbNotes/dbe.pdf) extensions in case someone wants to write a protocol description for XCB. Note: Multibuffer is deprecated in favour of DBE. It also seems that DBE is deprecated. See [this](http://lists.freedesktop.org/archives/xcb/2006-August/001854.html) thread. + +A conversation with keithp indicates that his current thinking is that the right way to do double buffering is via an explicit copy from a separate pixmap. This is portable to absolutely everywhere, and requires no magic. Probably there will soon be a convention for the compositing manager to handle the double buffering on systems where one is running, since it needs to buffer anyhow. But this would be in the future. |
