The Xorg leaks are very likely the X resource leaks described in bug 1050610 and bug 1057263. Those will bloat X rather than bloating the offending process gtk-window-decorator.
The issue with opening the dash using lots of memory is bug 982434.
If you think you have a new leak that is none of the above, please run this command so we know what package versions are affected:
apport-collect 1061792
