Why does my mouse keep doing the loading sign?

I have been having a (hilarious) problem with my mouse pointer recently, in which it will not stop switching between the “working in background” pointer and the normal pointer. Why is my computer doing this?

For reference, this is happening on a Lenovo Thinkpad E480 with Windows 10 Pro. See this picture for reference.
