Differences what I can see:

* Copies from cairo render target and backing pixmap were done with render
composite in 1.10. But 1.12 changes those copies to XcopyArea.

* 1.12 create a 2nd backing pixmap that looks like it should be the window
instead. That means the last copy to onscreen memory actually goes to X pixmap
that is never show in screen.
