Cursor none is not working?

Hallo,

In my site i have a custom cursor and i want to hide the default cursor, so i selected the Body and set the cursor to none, but its not working in preview the cursor is most of the time visible the default cursor disappears only a view seconds, no matter what section on the page, the behavior of the cursor visibility seems pretty random to me?

I already tried to select (Body all pages) and then set the cursor to none, but its the same result.

What i am doing wrong?
