(Get the code!)

The *bug* is neither in libcairo nor in any gfx driver, the bug *is* in xorg (see headers of this bugreport and the whole bugreport posts itself). It just happens to be the case, that a new feature in libcairo makes that bug appear and a performance-wise sensible fix in at least the radeon drivers does prevent the bug from facing for now, but the *bug* is still there in xorg. No idea if the same kind of fix would work for nouveau and the others but that fix is just a "workaround" for the issue.
That may not be important from a users point of view, but when it comes to assigning bugs and actually fixing code it is imperative to do it at the right place, obviously.
What Julien tried to tell you there is this: "Whatever issues the nvidia driver may have, whatever bug in whatever code is visible with the nvidia driver is of no (deeper) interest here". Quite logical, as we can't do anything about it as the driver is closed source and ALWAYS adds an unpredictable element in the whole matter which foss devs try to avoid if possible. And a side note, some foss devs may even be a little bit biased there, as shocking as that might sound. ;)
