Hi, I'm the one who posted the confirmation you are linking to in your post. I've just tested it with the xorg nv drivers. It's still there so it has nothing to do with the proprietary driver.
While the minimize animation is in progress, the mouse is sluggish and is "jumping". The animation does not last very long but this jumping is quite annoying because it let's me think that something's wrong with my pc. Other than that, I've had no problems with the installation. I can also confirm that there are some dependency problems in the packages. I can't install several development packages: The following packages have unmet dependencies: libx11-dev: Depends: libxcb-xlib0-dev but it is not installable -- Syncing and merging X.org 7.2 https://launchpad.net/bugs/84731 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
