Mouse over devices

I tried, and indeed, the graph continues to appear :frowning:

In fact, i use a monitoring with a screen and a computer on W10, with autostart and on each boot, the windows mouse, not used is on strict center.
And, logic, i have always a device located right under the mouse :laughing: (Average 100 devices with fit zoom)

So, I try to either make the mouse disappear or make the graphic disappear.
