Hot corners work unreliably on Ubuntu 16.04

[Robert Smith]

After enabling hot corners with the Unity Tweak Tool -> Hotcorners -> Select "Window Spread" for one corner, this change is temporary. After rebooting, this feature works unreliably between reboots (that is, sometimes it works and sometimes does not work). I have noticed that most of the time, you can force it by clicking on the desktop and then opening your applications as usual.

There is an old bug (https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1305438) about this issue but there hasn't been any activity for a while. However, this is occurring on Ubuntu 16.04.

Let me know if you need more information.
