Usually when using Windows people have several mouse states and each state have an icon and means something different. I'm testing a Mint 19 and I'm not able to see the states "application starting" or "working in background". Is there any way to solve this? Maybe using a different mouse icon set?
The cursor being used is controlled by each application, for any window or widget it displays on the screen. There isn’t a global cursor, so there is no state for “application starting”; applications can choose to display a “busy” cursor, but they have to take care of that themselves.
