I've got it and it's still leaking like a sieve.
With xorg-server 2:18.104.22.168-1 now in Experimental I'm not even bothering to touch Xorg until Nvidia fixes the tearing in Flash [if ever] or the sheer lag with each incremental update X produces that either breaks ABI for Nvidia or just makes everything slower.
