Renaming not working sometimes - Cursor not inserting chars in "New Name" field

Sometimes, when I want to rename some number of files it is not working at the first time.
What is happening is:

  • When I try to modify the NEW NAME, cursor behave strangely and instead of inserting what I am typing, it insert some strange (square) character.
    At the end I have to close the rename windows and reopen again and it works.

As it appear randomly I am not able to repeat now.
I was expecting this stop happening with some udpate, but still persist with the last one.
May be you can give me some idea to debug or get more info to understand the situation.

We don’t have any similar reports.

Do you have any software installed that modifies other programs or changes how the keyboard works?
