I can’t click on the menu because the white square is in the way, is there a solution?

I reinstalled but can not solve this problem…

What can we do with such a truncated screenshot?
Edit your question (= modify it) to add OS name and LO version. What is this “white square”? Does it move when you move the document window? How did you install: from distro repository, from LO official site, manually, …?

Thanks for the comment.

Bottom line, restarting the PC solved the problem.
