Same here. Gnome has very serious performance problems that make working with it on a daily basis a headache for me. I don’t even think they can be fixed any time soon as they seem to be structural. Unity 7 is rock solid, looks good and let’s be honest here, the out of the box experience is miles ahead of Gnome as it is today. I really would like to switch to Gnome, but every time I’ve tried, the stutters, the shell crashes, all the input bugs in wayland. I just can’t deal with it. I’m a software developer, I need my computer to flow like butter.
The Unity packages in universe work fine for anyone wondering.
