Why does the cursor disappear when typing?

Question

macOS

Good afternoon, on my macbook pro 13 retina, the cursor began to disappear in some applications or browser fields when typing.
About printing in sublime or input, textarea on some sites the cursor simply becomes invisible. If you move the mouse, it reappears.
For some reason I don't think this has happened before.
What could be the problem and how to solve it?

Answer 1

Everything was, everyone is like that. The feature was introduced about 3 years ago. Since it was possible to arbitrarily hook the trackpad while typing and the cursor jumped to another place, the function was introduced with the advent of large trackpads on macbooks.
You can disable the function here and suffer like in the old days)
