While the 2 commits do eliminate tearing here with nv50 that was brought back when using xmir/u-s-c, considering the current state of bug fixing it would be good not to create yet another bug in compiz
For 13.10 not using u-s-c is probably the best choice for users concerned about tearing & who have none with the current X, mesa, compiz & unity
Also to note that the commits did a decent job of eliminating tearing in gnomeshell/clutter, 100% gone with xmir/u-s-c, not quite 100% with just the commits (no xmir, u-s-c
Though Gs users can eliminate tearing completely with a simple env for clutter
If those commits are going to be applied it would be useful to provide a testing ppa to see how they do with other nvidia hardware & if they create any further issues other than noted previously with compiz.
