Linux Mint 18 Mate memory leakPosted: September 9, 2016
You may experience your Mint 18 Mate occasionally getting slow and non-responsive, with Mate panel freezing or mouse pointer moving slowly and in jerky fashion.
If you run top, you see that that CPU usage is constantly up, with mate-settings-daemon hogging close to 100%.

If you see something like “unable to create file ‘/run/user/1000/dconf/user’: Permission denied. dconf will not work properly.”, a memory leak causing bug may be at fault.
The bug makes wrong permissions to be assigned to the file /run/user/1000/dconf/user , making it non-writable for your processes.
Fix it as root by making the respective user to own the file respective file, e.g. /run/user/1000/dconf/user , and killing and restarting the mate-settings-daemon .
