Personally, I don't think this bug is fixed yet. Desktop Linux still lingers around 1% market share, and while Android, OEM involvement and new AAA software titles, I think we still have a long way to go.
Oh, well. Debian fanboy's 2 cents.
Wayland is going to be the best thing to happen Linux ever! This is what's going to make Steam games smooth, make graphical lags and glitches nonexistent, and set the stage for better graphics drivers from graphics card venders! I'm stoked! Can't wait for this to go mainstream!
If anything, I think Canonical's being a tad bit childish. They lock us out of alpha/beta test to develop in "secret", and are in the process of turning their OS into a shopping cart. What next?!? Close source the project? It's the very reason I'm typing this from my Kubuntu machine and loving it.:-)
