I started noticing this shortly after applying UP8. mate-settings-daemon has a severe memory leak - close to 1GB/hr. This renders the system almost unusable after a few hours.
I can kill the process from Task Manager or terminal, but it comes back immediately and continues to leak memory.
Here are some of the system specs:
