Everyone says that gnome-shell uses much less memory than unity shell. But I find it is true only for a short period time.
Under Ubuntu 11.10, gnome-shell 3.2, the cron "gnome-shell" uses about 40~60MB memory when logging in. Then it keeps increasing slowly but steadily. Several hours later it uses memory about 600~800MB and sometimes up to 1GB !
I've heard such "memory leak" on Internet. Is it a native bug of gnome-shell? How to fix it?
